Can anyone tell me if this is correct-when fitting 1200cc secondary injectors do you just enter 1200 in to secondary size and +0.04ms on the lag time.This is the way i have entered it in to the pfc but when i hit second turbo range it keeps choking the engine with fuel or so it seems(splutters and resistance to rev freely)or does the map need to be adjusted in any way to compensate.Thanks in advance Roy uk.

 

That is what I did originally without any problems, and so did many more PFC owners.

What all engine mods do you have that only affect air intake, fuel, or exhaust?

 

I have found out what was causing the spluttering,the secondry flaps in the throttle body were stuck closed causing it to run mega rich.Roy.
