i am curious too, and you would be amazed what the stock computer can do to compensate for large injectors

 

ok guys just so you know im stupid the car is fine i didnt have the MAF in. and the stock ecu should be fine look at dynoflash they run the stock ecu with bigger injectors. anyways thanks and will keep you guys posted.

 

Huh?

Reflashed ECU's injector compensation are set for the specific injectors used. People don't roll around town with ECU's set for 560cc's while using 780cc injectors.

 

Exactly. If you are running the stock ecu code or a ecu tuned for stock 560's , then put 720cc's or the like in, the thing will backfire and sputter as soon as you hit full boost at WOT.

Ask me how I know.

 

edit: I was going to tell you to make sure your maf is plugged in and if it was your b.s was out of phase. Glad you got it figured out.

 

glad you got your car running. hope it become a monster when shiv is done with it

 

no i ment that the ECU is scaled to the injector size that i have. its running good, but i only have a .8 bar spring in the waste gate so i need to get a harder one befor my tune. JAMES i will be in tacoma tonight are you going out there.

 

nope im trying to save cash right now so i dont go no where
