That is my first thought as well. Did you check the fuel pressure?

The fuel pump, I will hook up the fuel gauge and take it for a run and find out. I just put 80lb injectors in. The boost is at 8lbs. So. I should be around 51lbs at wide open throttle right? Is there anything else I should look out for. In the frame with the knock at wot the tps was at 2.74 should I be worried about that.

BLM's at idle with the engine warmed up. Steve and I are guessing at the fuel pump...that's why Steve's asking for fuel pressure. Fuel pressure should be no less than 1 for 1 with boost.

Static(with vac hose off) +boost = needed fp if the pump is keeping up. Another thing that threw me was the maf gr/sec reading. At wot a stocker should go to 255.and i think an upgrade maf w/translator should go to 255 unless you have some thing more fancy.

The maf will not go to 255 at 7 psi. It takes around 17 psi on a stock set up to reach 255 g/s

The ECM ignores tps IF the ecm has commanded PE which is determined by LV8 which is set by the chip maker.  I would go thru the process of setting it to whatever your chip maker specifies so it will be able to be programmed.

I'm pretty sure I'm getting 255 and I'm thinking I'm only around 14psi. Tt chip and 42lb injectors. Maybe that makes it different.

TT has an automatic lock on at a certain point, that may have something to do with it.

If he had 7.8 psi at 178, then 14 psi would appear to be 240 gps...which sounds about right to me and that should lock into wot on Eric's chip...IF, I am doing the math right...that's a really big IF lol

If the PL file is showing PE ticked on the data page, it should be fueling correctly-again I think

Rob, where are you located?  May have someone close to you that may be willing to meet up to help get the base numbers dialed in
