You will be in the low 10's for sure, and most likely in the 9's with ~18psi. The difference between 10, and 15PSI is huge on a T76. I can't imagen what 15PSI down there at sealevel would feel like. What's that thing weigh?

Boost only, Daily driver.
Truck weights about 4280lbs with out driver, I already have some race seats and a lift off hood so it might weight less even after the cage its done.
I just know that when I had it at 7psi and then I would put 12psi it would make a huge difference, we'll see what it does with 15psi and if Allen wants to try 18psi he is welcome to do so.![]()
