Stock Injectors = Maybe? Big NO?

There's no way you're maxing the stock injectors at ~6psi of boost. I can maintain 11.2-5 at 10 psi and 5k rpms, so you have plenty of room.

I don't know how you're tuned, but if you're in closed loop there won't be any problems with the ECM running larger injectors. Otherwise, you have to tune for them in open loop.

I'd recommend running an open wastegate until you're properly tuned. Stoich is too lean while under boost conditions. If you were only making boost in WOT then sure, but with such a small turbo you're probably making boost during part throttle.

Perfect! Exactly what I though!

You are right, closed loop adjust itself with the o2 with bigger injectors. But still, its not ''that good''...

Let's say that is alright with the boost, you just need to be very carefull with the throttle. NO WOT at all!!

thx!
