So I took the car out today for a long spin with the new Racechip Black installed. I haven?t regapped the plugs yet but I also didn?t experience any issues. I run 93 octane here in Canada and so far so good but I still might either replace the plugs or regap just to be on the safe side... In race mode selected on the chip and sport on the car it is a beast. Turbo lag is gone and it responds very quickly with a noticeable increase in power. I put approximately 500kms on today so stay tuned for long term results
