hfc, uprev, spacer

[Will370z]

I went for hfcs purely for the noise, great combo with the milltek and the car sounded glorious. One of the best additions i ever did.

 

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,

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

I gained a consistent 2 mpg increase.

1000 miles pre modifications 23.9

1000 miles after 25.8

 

Been 12 months now and still the same.
