2017 mustang hitting max map at 4800 rpm

[onefastt]

Calc map max is set at 31.88 which I believe is 107.9 kpa. im hitting 107.9 kpa at 4700 rpm. Car is 2017 mustang gt NA with holley intake manifold. Do I need to raise the calc map max or change something else?

hitting 107.9 kpa at 4700 - NA? Sounds to me like you are overestimating the air-charge. maybe murfie will chime in.

Air charge in speed density?

Either you have way too much airflow stack into your maf transfer, or you havent messed with the speed density at all, which you should do when you change the manifold to tune it "properly." What load and what lb/min are you hitting at 4700?

Pretty sure its in the Speed density tables. I have been messing with them, but I know they need work. My maf transfer is from JLTs tech department.

Adjusted the speed density table for mapped point 13 and now it goes to 107 kpa at 63% absolute load and 39.41 maf lb and 6300 rpm
