i think i know why my mph is a tad low in the 1/8 and the 1/4. i made some logs today on using the maft-pro and my boost is moving up and down on WOT pulls. i have my car setup for 26psi and i will see anywhere from 22-26. the car is not spiking and can't feel it. i had to review my logs to find it.
it's like this... 22,23,23,21,25,24,24,26,22,24, etc.. through the run. i wish my boost would hold rock soild.
is this just the nature of the beast with an internally-gated turbo. do i need to port the wastegate opening? i'm running the joe-p MBC. i have the GM boost solenoid for the pro, but i haven't used it. the solenid is very hard to dial in and that is why i haven't used it.
is there anything that i'm over-looking?
