I'm not one for leaving reviews straight away and thought to leave a review after some time has passed. Got the tuning on my Audi A4 (petrol) end of August '25 from 148hp(?) to 170, not much, but I do feel the difference. I'm not a race head, but car feels like it's been put in an extra "Sports" mode, but sure, you can only do so much MPH on the roads anyway, and I had a wee "flat spot" between 2nd & 3rd gear which has now gone.
Also got the engine carbon cleaned at same time, I thought this was for diesels only, but there you go. Although the car had low miles, I just got it done while it was there.
How long did it take? Well, after asking all relevant questions, I took a dander down to Audi showroom for a look around, so say about 1+ hour or so, but Mark phoned to say the car was ready. 😁
As for Mark himself, as said, answered all my relevant questions & concerns, no pressure whatsoever & job done in good time. Price was reasonable (& cheaper than what my local auto-spark was going to charge me).
Would I recommend? Just look at the reviews. Thank you.

Had my bmw1 series done by these guys recently, great service, professional guys.
Car is running like new.
Many thanks

Highly recommend. After sales service from Mark is excellent
