I don't know if there is a problem or not but I sure hope would like to know.
I just had a VF34 with STi inejctors installed. I took it for a testdrive and to my disappointment, it's alot slower than with a stock turbo. I don't feel ANY ooomph and it's hard to tell when the boost comes on. That's not all. In 2nd gear, I go WOT, around 4.5k, engine starts to hesitate and the rev goes up very, very slowly.
It hardly breaks 5K with the pedal down. When I accelerate slowly, it goes over 5K without any hesitation but it still feels slow.
Boost is fine and it seems like there's no leak. I have no way of knowing how the car doing though since I don't have any diagnostic tools.
I heard that it should be running very rich with bigger injectors and pump but would running rich cause this kind of problem?
My mods are Stage 0 WITHOUT Unichip(being reprogrammed), M2 turboback, Samco IC hoses, Supra pump and AEM CAI.
My Unichip's coming back next week but I want to know if the install was done right and there's nothing wrong.
Would waiting it out resolve this problem? Will ECU eventually learn the new setting and correct itself?
