That's a lot of boost

I only hit 15psi in 3rd gear or at shifts. 1st and 2nd gear I am at about 14psi.

Granted that was only for 1 run. Prior to that I usually never ran more than 13psi. Remember though that all 15psi is not created equal. LOL

Ohh and I wanna see some damn dyno #s or ETs! That thing has to be be fast!

I wish I had a reason to get that "PSI envy" shirt.

Boost is easier attained through higher gears. 1st will never be as high as your higher gears.
