That is the scan. The engine breaks up heavily over about 5000rpm. Cylinder five has a high misfire count, and cylinder one is moderate. I am attaching a screenshot of the misfire counts so you can see what the deal is.

Cylinders one and five are not on the same coil, but are on the front bank. Cylinder three is fine. I advised to swap the injectors for cylinders three and five and then we'll re-scan, and go from there. But, I think it's rich, and then, look at those IPW's, too!!! They are 42.5 pound injectors. He runs about 15psi, if I remember right. It's got a HV3, Cartuning turbo kit with the T76 (I think) turbo, intercooled with 1.9 rockers, 180* t-stat, and the plugs in it tonight were 103's. The plugs and wires are brand new. This problem appeared after the HV3 install.

The fuel pump is a stock GT pump yet. He's got the alternator rewire, and I believe is going to order the fuel pump rewire, and a bigger pump. It appears to be running out of fuel, either from a lack of injectors or pump.

What do you guys think?

By the way, those misfire counts are from a total of about 45 seconds of WOT running.

PT-61 is the turbo Joe. I got new wires, plugs, icm, swapped injectors Joe gave me, coil packs are new. Still studders. Could be bad gas from storage. Got a new zzp filter and a fuel pump rewire, and fuel press reg. We'll see if new gas helps. Sure hope so!
