I'm tuning on a procharged application with 8psi of boost. I have the commanded PE set to 12.0. On the dyno it is adding fuel via LTFT @ WOT after a couple of pulls. The actual A/F ratio is deep in the 11's.
Also we're going to 12psi with this car should we forget trying to play tricks with the tables for this and go to a 2 bar sensor and tune?

Thats why you have to tune the WHOLE range from idle to WOT and not just WOT. If the fuel trims see a lean mixture before WOT, it remembers and locks into those values of that FTC at WOT.
