I think the garage that installs the superchip for you should have a 7 day (or something similar) return if not satisfied policy.
A company called Demon Tweeks installed mine, no rolling road involved though. The driving experience may have slightly improved but it was all suggestive, maybe my expectations were too high, see what you think?
The induction kit, 'may' have improved perfomance, but it was when the car was going at speed, not pulling away from standstill. The lack of power I experienced when pulling away, easily dulled any 'suggested' power increase further up the rev range.
If they do a return policy, go for it you may be surprised, if not you can always get your money back....
AutoDelta will recommend that you upgrade the panel filter when using the carbon air box.
