Procede v4 with FBO - boost level question

Hi All,

What boost levels were you guys seeing running procede v4 autotune with FBO (no meth)? I have been seeing around 13-14 psi @ WOT on the procede gauge. Perhaps slightly low due to crappy CA 91oct gas? Or possible boost leak?

(plan to upgrade to v5 once autotune is fully up and running)

thanks!

Autotuning is already fully up and 100% working on 12-17 with v5.

seems pretty normal for crappy gas.

13-14 psi is what I got on 91 when I had stock Turbos with the Autotune maps.

Sounds right. I autotuned to 15.6 psi on 93 octane FBO (stock exhaust).

when did the v5 release autotune?

Im running a unlocked v4, and have been waiting for the fully functional autotune v5 to be working.

Also did they figure out the drivability issues with the 6at yet?

+1. That's about right. If you aren't running Shell or 76 brand, give it a try. With Chevron or Valero, my car would always autotune to 1psi less.
