Hey guys, I've got a single T3/T4 turbo on my Jzz30, currently boosting about 12psi. The turbo itself is good for 25 pounds, I was wondering how far I could push the standard ECU before I lean out my engine? Just about everything has been done to the motor to make it nice and fast, all I need is a fuel cut defender so I can go over 15psi.

well, considering the factory ECU has no maps after 14 PSI (fuel cut) the fueling is going to get progressivly leaner the more boost you add.

Get a ECU and do it properly

Nah it's all not been done by me, I'm selling it shortly so I can personalise my own soarer and start from factory spec so I know t's all been done right, so not too concerned about spending heaps on this one.
It is pretty nice though, goes like the clappers.
