Octane Tuning Avis 

I recently bought an Audi A4 3.0 TDI V6 Quattro with a fairly sketchy service history. Within a week, I was getting an EGR fault code. I suspect the previous owner had just deleted the fault codes and hoped they wouldn't turn up on a test drive.

I spent about another week researching common issues and problems with this engine. Finally I decided to get the EGR sorted and the engine remapped.

I chose Octane Tuning as the website was quite nice, it was quite close and the reviews were pretty good. I think I may also have been a bit drunk and just had to pick somewhere after endless Googling...

Having said that I was still in a wary mood as I drove down to Haddington and I had a list of questions to ask Euan before he started work (hey, a week of Googling pretty much makes you an expert right?!)

He took my questions in good spirit and I was placated. But most importantly he seemed like a genuine guy who just liked tuning cars. So I left my key and went away for a dander around Haddington.

I've never been for a dander around Haddington. It's so posh. And quite lovely. An "All Creatures Great And Small" kind of place. Apart from the industrial estate and the cheaper houses on the outskirts of town...

If you haven't been you may as well throw in a remap and a weekend away at the same time (no fee was paid for this review).

Anyway, I'm finally writing this 2 weeks later, after having done about 600 miles.

And...all is well.

On a steady 70 mph run I'm getting 48.7 mpg, which is bloody good for an old V6 from 2004 (and which has a satisfying vibrating burble when stationary).

Around town it's a fairly dismal mid 20's but I can accept this.

There are no warning lights and I can see that the DPF is regenerating via OBD scanner.

Can I tell if it's faster? In all truth no. But that's because I didn't really boot it prior to the remap. And it was quick anyway.

Post remap, all I can say is that if I boot it from virtually any speed then everything becomes illegal or scary within five seconds. And that's fast enough for me on a public road in a pretty big old barge, even if it is a Quattro. I haven't approached the limits of this car. If I do I'll probably end up in a field, banned or dead.

And finally, Euan said if I had any problems I could come back and see him (this is good as I'm just about to get a main Audi dealer service and hope they don't muck about with the map). He saves the original map so it can be restored.

Now wondering if I should get the gearbox remapped so I can die 0.2 seconds faster.

Just kidding God!

Excellent, friendly and efficient service with helpful technical knowledge and advice. Remapping gave significant improvement in performance for the price of a routine service. Highly recommended.

After comparing lots of misleading claims, from other companies I asked Euan for some information regarding remapping my A5 2l tdi, I was contacted within the hour and felt at ease discussing the remapping without any sales pitch or pressure.

To cut a long story short I am delighted with the results and would definitely recommend Octane Tuning to remap your pride and joy.

Octane Tuning, Excellent. I spoke to both Euan and Tim separately and got good advice from both guys without any hard sales. I spoke at length to Euan about the IXsound active exhaust system and he was happy to discuss the system through with me. Over a couple of calls we went on to discuss my car I found the information I got from him was accurate and above all as I have said there was no hard sales. I decided to book myself in for an engine re-map and was 90% certain I wanted the IXsound system. Euan was more than happy to let me hear the system on my car before I commited to buying the system. On the day I arrived a little early, both Euan and Tim were working in the garage that day and were really professional. They set up the IXsound system on my car and demonstrated it and I knew right away I wanted it. Years of trying to get a decent exhaust note from a diesel engine without success, I can’t rate it enough. Both guys took great care with my car and it had to be right. They talked me through everything they were doing I found both of them very knowledgeable. My car sounds amazing and following the re-map I have noticed more torque, it is still to early to confirm if I am seeing any fuel savings however: I am sure they will come.
In short, I can’t recommend Octane Tuning enough, honest professional guys who do what it says on the can. Thank you.

Euan was friendly and knowledgeable. I left my BMW Z4 for a few hours and hoped the car would improve. Absolutely transformed the car with accelaration, torque and fuel economy. Worth every penny. Approx 184bhp to 260bhp and 270nm to 400nm of torque. The car performs to its true ability now and what it was built for. Thank for the 5 star service.

Great service from Euan at Octane Tuning!
Absolutely delighted with my stage 1 remap and gearbox tune.
Don’t go past Euan for any performance upgrades, you won’t be disappointed!
👌👍

Tim was really courteous and knowledgeable. Very professional and smooth sailing for my requirements. Spot on would definitely deal again.

My DPF was unable to clear itself so I googled around and come across Octane Tuning, I contacted Stephen and he promptly arrived and sorted my issue out straight away. Will be using Stephen’s services again very soon as I just realised he can also do vehicle remapping services. ⭐️⭐️⭐️⭐️⭐️

I called Euan to enquire about a tune for my Audi A4 3.0 TDi and was impressed by what he said, so drove down to see him the next day.
Met Euan at the unit, had a brief chat then left him too it.
2 hours later my car was transformed, I hadn't appreciated just how sluggish the old dear had been, great pull through the range, getting more MPG and the car is just running so much better.
Euan even refilled my screen wash too :)

If you're looking to have your car tuned, you cannot go wrong in giving Euan a call.

I took my Volvo XC90 into Octaine Tuning to have an ongoing problem with the DPF looked at. I had already had the car in to two other garages regarding the issue, both saying I needed a new DPF. However, that very competent Dougie managed to work his magic on, without need for replacement. He gave me a full diagnostics, explained what the problems were and how he could fix them. I felt reassured at all times. My car had been in and out of limp mode some time causing severe loss of power, but I drove away from Octaine Tuning with the car feeling alive and full power. Delighted

My mercades amg line had a stage 1 remap today and I couldn't be more pleased with the power and torque now

Great service from start to finish. Had an issue with my induction kit not working on my car but Euan assured me he could correct it which he had. Also did a great job increasing the performance of my car with his stage 1 remap. Honestly couldn’t be happier, could not recommend enough!

Had a Stage 1 remap on my diesel Volvo V40. It's like having a new car.

Not too many extra horses (+20 BHP) but the increase in torque and responsiveness is just incredible.

Euan is a proper gent and I'll be bringing all of my future cars to him to work his magic.

Oh my god! It's like I have a brand new car! Feels so much more alive and eager to be driven!

Euan was fantastic. Very knowledgeable and is clearly passionate about what he does. Took around 2 hours and the difference is night and day!

Definitely recommended!

Got my fiesta st stage1 tuned on Saturday morning I am very happy with the work carried out and the results would highly recommend this garage and the friendly guy Euan was very knowledgeable and helpful

Had my Audi A5 in getting stage 2 remap, excellent job car is now running a lot better and faster. Excellent advise and service. Would highly recommend to all that needs more power.

Had my VW Campervan in for mapping increase of 55bhp which is fantastic. Euan provided great advice before making the booking. Requested an earlier booking time which was accommodated. Overall I’m really pleased with the result and worth the round trip from Glasgow

Had my pride and joy Q7 with Euan today for a Stage 1 and EGR delete. To say its become a serious animal would be an understatement. Could not be happier with the results. Euan's knowledge and skill is second to none and a nicer gent you could not meet. My A5 will be next to get the Euan treatment. Thanks for all.

I taken my 2l titanium ford smax here for a stage 1 remap as I felt my car was very sluggish. I was talked through the whole process which put my mind at ease. The process taken 2 hrs and I must say I am delighted with the outcome. Every gear is so smooth now and also a lot more responsive. It feels like I'm in a different car. Would highly recommend this company.

I have a citroen relay 2016 camper. It had always been slightly underpowered. When an ad blue fault came up I took the plunge with octane tuning. It's a much better van for the wisdom and knowledge of octane. No faults and perfect service.. Highly recommended and thanks again.
