Default Measuring back pressure with 38 lbs of boost.

We're heading to GA next weekend for lights out 7. We're going to run ODR. Finally installed back pressure sensors to find out what we have going on. How efficient we are also if we're out of turbo.

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.

Make sure to test the sensor against your map sensor, so at least you know the two are calibrated together.
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
