Esmeril Turbo Issue
Hey everyone,
I have my Esmeril kit installed and we are hammering out the detail for tuning. Jeff (MazdaManiac) and I have using the COBB I bought from him a few years back. Our Issue is with the car going full lean at 3k RPM.
We swapped the middle injectors for 1000cc and took those yellows and put them in place of the reds. I also installed the 300lph fuel pump that came with the kit. The car idles amazingly well, but as soon as I get to 3-3500prm it wants to shut down.
We took the fuel pump out today and checked everything, same with checking the injector setup and wiring. We just cant figure this out. I can only think that the fuel pump is our issue....
PLEASE HELP!

Turblown "There have been reports of issues with that pump on Rx-8s...
Does it do this while free revving or just under load? Could be a lot of stuff..."
-It has been doing this since the first start of the motor. It does it both free rev and under load.
TeamRX8 & Charles R. Hill-I'll have to look at that valve, but the PCM should be ok at this point. This problem has been going on since the very first start with the kit on. I think we will try the old fuel pump, as its easier to swap out than trying to test for fuel pressure here at my shop.

Update.
We swapped the fuel pump and it seemed to be running a lot better, then once it warmed up it started doing the same thing again. Out of sheer guess work, we unhooked the MAF and started it up. We only did this for a quick trial, but the engine didn't bog down and revved freely through the entire range.
With this being a blow through set up, what options do I have left? Should I try and order a new MAF? Let MM/Jeff know and have him advise me?? Maybe he will read this soon....
Thanks for any ideas.

I have a new set of colder plug, but I was waiting to break in the car a bit before I put them in.
From what MM told me, the STFT are going to 0% at the 3-4k rpm range.
