The fuel cut comes on when you go 0.25 kilogram/cm2 over your boost setpoint. What do you have boost set at, and when did the power loss occur?

Well i went to sevenspeed today and my prob is fixed. Since i still have stock injectors in, my power FC was set to cut after 11 psi. Well in 3'rd and up i was getting boost creep above 11 psi and my power FC was shuting down the engine. So till my 1300CC inj go in george moved my boost up 0.05 so the cut wont happen in 3'rd and a lot latter in 4'th. Thanks for the help thou guy's

why do you need 1300cc injectors though?



I can run 1.2 bar maybe more

I have a T04E, Trust 3 row intercooler,

big side ported motor, ported and polished

intake manifolds and the throttle has been

bored out too, I have no airfilter(more air)

and a full straight exhaust and a GTR fuel

pump.



STOCK INJECTORS all around...

What do you have as far as fuel pressure? That might account for some of the fuel.

Stock injectors will take you to about 13 psi before you start pushing the safety margin. Its not good to run them at 100% duty cycle. This is with stock turbos though. His to4 will be flowing alot more air even at 10 psi. You shouldn't need ignition untill you are over 20 psi boost. If you are having breakup then your stock ignition has a problem. What plugs are you running? Any car with a decent amount of mods should be running 9's all around. For higher boost you can step up to 10.5 race plugs.
