h*lp from you!

[Espen Hilde]

Hi!
If you have doubled the hp of your engine you need to widen the dynamic 
range of your injectors, stick with peak and hold ,get some driver boards
from 332 efi, soon there will be a group buy I think. Make new fuel 
line and clamp down for the injectors.Or get an other oem ecu that can
drive the low imp injectors.
Just my oppinion.
