Well, for a reference, my 4.8 with 10psi of boost at 6200rpm only gets to 1.08 g/cyl. g/cyl is actually an airflow number not a throttle position number. More PSI of boost and RPM= higher g/cyl. I think a stock n/a 5.3 only get to about .64 to.68 g/cyl.

 

Gms/cyl = (Maf (g/s) x 15)/ rpm

At 10 psi I can see 1.22 g/cyl at 5600 rpm and maybe even a little higher say 1.29 g/cyl. Because the logging software is so slow it is hard to get a really accurate #.

 

Thanks guys-Great info
HP tuners in my future
