fuel cut?!?!?!
right when I hit 15 psi the car just cuts out and jerks back as if there is fuel cut. I don't know what the fuel pressure is at the time that this happens but I looked at the injector duty cycles and they seem to be showing fuel cut.... where can I change this setting?

Two questions:
1. What is your boost setting on the PFC? The PFC enacts fuel-cut if you exceed the boost setting by 0.25 kg/cm^2 (3.5 psi).
2. How can you tell you're hitting fuel-cut from your injector duty? You don't change your injector duty, you change the fuel maps. The injector duty simply reflects how hard the injectors are working.
EDIT: Just reread your sig -- you are running 850/1300 injectors with the stock twins at 15 psi? Your duty cycles should be very low, probably under 65%.

okay....just a little new at this pfc thing. the boost setting is .80 bar on the power fc, I think I'll raise it to 1.15 that should take care of the problem. I'm still running base maps, I need to get this bitch tuned.
Thanks for slaping me into shape berg...

wow..... That freakin worked, boost spiked to 20 psi. these turbos actualy have turbonectics modified compressor wheels and a different turbin wheel.. or so bryan told me when he rebuilt them. I just need to make a proper boost controller. I'm using a home depot style garden hose fitting right now, I just ordered stuff from mc master today.
Thanks for the help!!
