Do you think my fuel pressure is too high? I brought it to the top end of the specs for a gsr according to my shop manual. The manual says the pressure should be 48-55 psi.

I think I got it worked out. I found and old adjustable FPR in my garage. I brought he fuel pressure up to 55 PSI with the vacuum pinched. I'm now seeing results that I expect.

I got the wideband hooked up for data logging, and it seems to be working pretty well. I did some tuning in the fuel maps an realized I'm approaching 100% duty at 8000 rpm while still running a bit lean. I'm starting to think my problem is with the fuel system.

I'm pretty sure my fpr is from a gsr ...

What band wideband are you using?. Use a different wideband input in the parameter settings (eg. D10...D12...B6) as your datalog is showing a rich mixture. Use close loop when you are finish tuning the car.

I have an innovate wideband but have yet to hook it up for datalogging. I've only had the ...

Here is a short datalog.

I have an EG with a GSR block that has been converted to an ITR. Here is the setup

ITR pistons, Intake Manifold, Head, Throttle Body
P28 ECU with s300 running the ITR base map
Intake, Header and Exhaust.
Innovate wideband which I have not hooked up for data logging yet. The wideband is not ...

the combination of the ITR block and the GSR head gives you a higher compression rate, so the air/fuel-mixture will be compressed more and gets warmer before detonation.

due to your I/H/E the flow should be better than stock, that provides you more air into the chambers than regular.

adding fuel ...
