How well does your car start/ idle?
Those are AWESOME numbers for 12psi!

Thanks! The car starts like stock, even in cold weather and idles smoothly.
I posted the dyno vids in the build thread.

Did you build your diypnp? Or did you buy it pre built from someone else?

It is a Enhanced-DIYPNP from the Revenant/Brain group buy on MT.net. Full plug and play with extra features.

I thought so...

Would love to see photos of your engine bay and setup.

datalog of boost? strange looking torque curve- but great numbers for 12psi regardless

Here is a finished install pic from my build thread.
