Measuring back pressure with 38 lbs of boost.
Can't wait to find out how are new RPM Transmission works out , really excited to have them on board. We also switched to a air shifter . Looking to go a little quicker.
Or if there is a discrepancy you cant adjust for, at least you know how much it is
Running similar boost on a friends 4cyl car a few years ago with an old 6262 it was seeing around 58psi pre-turbine.
It still performed great though. Change to a 6266CEA did transform it though, spooled the same, but made a load more power and it dropped closer to 1:1
