"I was able to break and set the world record"
Tucn26s, McLarenLife user
I've tuned 5 of my personal Mclarens with them and all have ran great. I mod mine more than the average owner also not just a tune or dp and tune etc. I was able to break and set the 12c world record for the 1/4 with them a few years ago which was cool. I recently just got a GT and modded it again to go break the current record.
