I have a c32 woundering if I need fuel mods to go from a 65mm pulley to 62mm besides a retune from Eurocharge

 

Bigger fuel pump at the very least, injectors possibly depending on your altitude.

 

Ok thanks.

 

Chuk wondering what single or combination of mods got you to 114mph from 112 thank you John

 

Totally disagree with that answer...

 

What answer with fuel mods for the 62mm pulley on a c32

 

I personally belive you need a new fuel pump at minimum as well.. i ran a 65mm for years and then switched to a 185 pulley(which makes same as the 62) and i run 550 injectos, 55 fuel pump, and a retune.. some even add a looped fuel rail as well.. if you stay with stock fuel on 20+ psi that is not wise
