mini ram tuning questions
I started tuning my motor with tuner pro rt, my combo is in sig. i have most of the part throttle sorted out but i still have a stumble right on throttle tip in and while quickly revving it up. Ive added ALOT of AE fuel, but my scanner still shows it going lean. how much AE do i need?
Im also having a problem getting enough fuel in the motor. I have the VE chart maxed out at 99% from 4500 rpm and up. My o2 mv are only 760, i want 850 at WOT. what other ways are there to add fuel? I still have the stock fuel pump (i know its not a good idea and changing it soon) and i know this motors making a good 450hp, could that be my problem?

Definately your fuel pump. I installed the large Accell pump in my tank. PITA getting the tank out but in the end a nice set up.
