GReddy Kit - Fuel Pressure Problem??
Hi guys,
I recently had the GReddy turbo kit fitted to my 8 (2004 6MT). We had it on the dyno and seem to have hit a hitch.
We have been watching fuel pressure during the tuning process and seemed to have hit a ceiling of 3 bar (~ 45PSI)?? Under load, fuel pressure does not seem to increase? and increasing the injector duty cycle did not seem to affect the AFR past that point?
Any ideas??
Does anyone know what our stock fuel pump is rated at? is there a fuel pressure regulator involved in our stock setup?
Help would be very much appreciated!!

Ok, thought I had done all the searching I could before I posted this but alas not the case apologies...

Based on the info it seems like my piggy back is not kicking the pump over to "high" under boost?
would that explain the symtoms that I am seeing?
