Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Cutting out under boost/heavy load.



I just bought the LQ4 maf to put in because the MAF was running almost past 11500HZ. Possible spark gap issue im also wondering. Blowing the spark out?
 
got a wide band in the car ill ask again? fuel pump upgrade? injector upgrade? if not theres the problem. the maf file the right one? hows the trims?

see why you need a wb yet if you dont have one?
 


try gaping them at 0.52

when was your last tune up? id try some AL copper 103's or 104's. less then 15 bucks most of the time.
 


If you're maxing our your MAF it'll feel like an ignition problem, but it's not. I had the same problem with my Turbo T a few years back. I put an LS1 MAF and a translator (gotta love the old OBD1 ECMs) on it and no more cutting out over 10 psi. I eventually ran 18 psi in that car on the stock turbo. That was about all the stocker had in it. It was still pretty fast though.
