how much boost!!!!!!!!!!!

[duveeka24det]

I have a t3 turbo with a stock engine and a fmu 12:1. Yea i know its running rich, but thats all i have untill i get some 370cc injectors and a 255 fuel pump. I have a xs power turbo and external waste gate. I was just wondering how high could i take my boost and be safe. Im pushing five psi right now, but i want to push ten. If i turn my boost up to ten and im getting plenty fuel could i hurt anything.

do u have a wideband to monitor? I would keep upping it till your afr's look bad. Honestly u should just wait, dont wanna end up with a set of detonated pistons!

No i think mine is narrow band but im not sure, but it reads rich when im going down the road its topping my afr gauge out.

What kind of wideband? AT 10psi you should be retarded at least 3 degrees off base timing to be safe. At 10psi and stock timing if you get some crappy 93 gas your engine can go boom. KA-T lasting is all about the tuning.

Its probably not even running rich.. Get rid of the stock fuel pump for a Walbro 255.. I wouldn't even boost on a stock fuel pump.. Esp not on a FMU setup where fuel pressure is vital..
