Another HFC fan here too - my car sounds fantastic and I had plenty of compliments on the exhaust note at Oulton
Sorry to crash this thread but I've a quick Q re the UpRev - do you actually see any MPG gains? I've read conflicting reports and whilst a better MPG isn't something I'm overly concerned with any improvement will help to justify the cost of the UpRev to my other-half teehee.
Thanks,
S.
Mark at abbey said you could get mpg improvements, and i guess they could tweek the ecu to gain more. Imo though id still go for the optimal torque tweeks, no point buying a zed and then trying to make it fuel efficient
