Bluespark Automotive Avis 

Noticeable performance improvements, especially torque across the whole rev range.

Ability to change settings and remove unit when needed (servicing at Jag dealers) an added bonus.

The entire team at Bluespark were professional and helpful throughout.

Value for money!!!

I had been looking at getting a tuning box for a couple of months, did alot of research, watched alot of videos and did a lot of um and ah-ing before I settled for the pro + boost. Well, it arrived today and have given it a go and... Wow, I was not expecting so much power gains, not only that but feels smoother than before. My car is a golf 2.0 150hp which was an upgrade from a 1.6 golf I had before. Even in stock the 2.0ltr is no slouch but with this box I'm beyond shocked. As standard the box has two changeable settings (A to E and 1 to 9) it comes set on C and 6, I changed it up to D and 7 and that is the sweet spot.

I honestly didn't expect it to be so good. Another reason for the 5 stars is that even before I bought I spoke with Andrew at bluespark and he answered all my questions promptly and well, I wasn't even a customer yet and the service was fantastic. I cannot recommend this box enough, easy to install, loads of thrills and, as of yet no draw backs. I might be writing this a bit soon as I'm still feeling that tingle of excitement and awe but I can't see that subsiding anytime soon.

I'm going to get this on a dyno hopefully soon and see the numbers behind the gains. I cannot recommend this box highly enough.

EDIT: Just wanted to follow up having now had the box for over a month now. Need to ask, what the hell has your little box done to my car? I put a performance panel filter in and used an obdII to change the throttle reponse. I had a friend take it out for a spin ( a friend who drives alot of performance car and when I asked him does that pull like a GTD he said NO, it pulls like a GTI. Your box is amazing. I'm still smiling everytime I drive the damn thing. I've had a GTD and an ST try and get away from me and I could see the shock in their eyes when they saw me gaining on them. Its just too good. Can't wait to get it on the dyno. Thanks again gents.

I've had 3 tuning boxes from Bluespark now and they always go above and beyond to help, aswell as deliver a quality product. Will always go back to these guys.

Too good quality product. Good service. Great staff. Thank you.

Having spoke to the team at Bluespark HQ over email & social media for a few months to organise the date and decide which box to have fitted, they were able to answer all my questions.

On to the day of fitting and got my car straight on to the dyno no waiting around, they took three hours to test and fit the unit.

After 6 months+ of having this box installed its made huge improvement to the car, a little
Bit on MPG but the performance is huge, making over 35bhp increase.

Would highly recommend the company, service & products.

Very friendly bunch of guys who make every effort to get the best out of your car, I was amazed with the results and quality of work so I can’t recommend them enough.
