I just recently got my car done and tuned at A-spec, awsome place, anyway... So i took it for a spin and i suddenly got fuel cut at around 6500rpm. I tried it again latter and then it cut at 7000rpm. Pretty much the fuel cut is on and off between 6500 and 7000. I am running stock fuel system but on the power fc it shows me only 80%-90% injection duty when the fuel cut kicks in.

You think my injectors and dirty? Does the stock fuel system ususally do this? Or can it have something to do with the air temperature. My friend told me that the air temp is too low and the injectors cant make up for all the dense air...? (I have a Greddy 2 row FMIC)

I am planning to upgrade my fuel system next year anyway but till then have to deal with this. Ohh, and im running 11psi on stock twin.

THANKS _TOM

You are likely hitting the fuel cut built into the PFC. You need to either increase your duty cycles or raise your "target" boost values.
