ECU:How does it calculate Timing??

Hummm, is there something magical about 3k rpms??), I'm wondering if there isn't something in the MAF input loop with the ECU that could be causing your "goes flat in 3rd gear" . I'd also be interested to see what happens with your egts if you bumped the fp to around 40psi.

The EGT's are so high because the timing is slacked so badly... I know that for sure.

I don't think it is a MAF issue to be honest. the readings are steady and consistent.

I am almost wondering if it may be due to the fact that the ECU sees neutral during shifts?? I am going to try a few things this week to tinker with a couple things... here is what I have planned.

1. Dummy knock sensors, these will be wired to the engine harness and tied up out of the way... I will have a bolt through them with a low resistance wire to the engine to make sure they do not throw codes.

2. I am going to wire a neutral switch... So the clutch pedal no longer sends the ECU signals that the car is in neutral when shifting.

I will try and take a look at what you have posted Phil... Not too much free time on my hands anymore but I will try
