This is pretty close for P heads shaved .030". Maybe 1 degree too much depending on how much extra compression that gives.

I'm at 9:9:1 boosted I just changed the piping from the pmas mag t9 intercooler to 3in before was 2.5 no my cars running lean is there any formula I'm running like 13.0afr on 93octane at wot now wondering how much would 100kg of air change the wide and reading to? Not sure if that could be estimated I know you can read fuel error in closed loop at part throttle but not at wot. I thinking maybe I should multiply everything by 1.2 or something like that see what my wide and spits out

anytime you put a new meter on it you have to put in the new maf transfer
a 3" pipe flows 44% more than a 2.5" pipe
multiply the maf curve by 1.44

thanks for that I used the pmas transfer sheet but change the other piping from intercooler and made me run lean. changed a bunch of stuff of yours now mine idles better and at good afr at idle gotta drive it next see what it does then ill adjust maf for bigger piping meter was also 3in before but 2.5 piping and intercooler with abut 12 in of straight 3 in piping I add slightly more into the bend with 3in 90s and a 3.5in small 90 degree right at the throttle body opening but probably will but a 3in since that all I had for tb opening for a 90

Did you adjust crank pulsewidth vs ECT for your injectors?

yes actually I did adjust them I have the 60lb dekas this is what I running
-20 - 12.29
0 - 6.94
20 - 4.49
40 - 3.33
70 - 1.80
150 - 0.73
180 - 0.63
66534 - 0.63
I'm thinking the numbers to low in the 150-180 range. anyone have a better crank pulse width for these injectors

Play with it. If it stumbles during cranking then add a little. If it seems lazy like it's rich then take some pulsewidth out.
