2g MAF screw

A car can run fine with a blown headgasket I drove my car for 6 months with one it only blew coolant at 25psi and above I just filled back up after the track. (I was lazy that year) I would fix it asap.

I'v enever run strong. i've been able to start and run to the parts store for another gasket. The old v8 guys were like WTF ! But You can't run "fine" or equal pressure on all piston tops. . . pressure is being lost into the waterjecket, oil passageways, or another cylinder. Running right includes running WOT. . .

when the head lifts a little you are loosing pressure

This is a HUGE deal. A lifting head will miss on all cylinders where the head flexed and lifted. . .

So you think i'm good on the head gasket? At WOT my car pulls and pulls...

If you don't see mixture of of oil in coolant or vise versa, your HG is most likely OK but it wouldn't hurt to compression test just to be safe since you have been running with high coolant temperature, excessive timing advance and most likely knock. Here are some of the major effects of too much timing advance under heavy load which can explain some of the problems you're experiencing.

1. Knock, the most serious of them all.

2. Lost of power, resulted from combustion pressure working againt the upward stroke of the piston.

3. Much higher combustion temperature, which explains your overheating issues.

4. increase in combustion pressure.

These are all very serious issues that can not be ignored, your options are simple, either go with smaller injectors or go with better tuning device that does not rely on "reporting false airflow signals" to compensate for larger injectors.

AFPR it is. I will buy one from the site at the end of the week. Thanks for all your help and vast knowledge.

No problem, I would suggest that you go with 255, AFPR and a logger. Make sure to taflon both the vacuum fitting and adjustment rod as they will leak, do not turn your fuel pressure down too much as it will affect spray pattern and fuel atomization, search and find out how to calculate injector flow rate in respect to fuel pressure changes. Good luck.
