    Looks like fuel limiter.

    Your limiting fuel in several places.

    What RPM do you want full fuel to?

    I just need it to fuel to the wot shift point. I believe it’s at 3250

    I was just going to tell but it was easier to just change them.

    I changed like 13 tables so look at the differences using the compare tool in EFILive.

    You should have full fuel up to 3250 but you were limiting quite a bit before so be careful, I don't want you to break anything.

    On the main injection pulse i capped it to 3000uS. The factory table will hold the injector open all day if your cp3 can't keep up.

    Another thing I changed was boost error thresholds. Probably not the issue tho.

    Well I got a chance to load the tune and go test and catalog it. Wow what a difference. How my tune was I was defending pulling a ton of fuel. I really appreciate the help. I haven’t updated my sig but I should be good to not break parts. I have a comp 2 firepunk transmission and arp studs with Hamilton springs and push rods. Thanks again arinkuddy.

    Good deal glad to hear it's running better. There was just some stuff in the way of your goal. One of the biggest was probably the barometric fuel limit.

    Actually it was Pedal Position to Desired Fuel and Fuel Limiter, Barometric, Table 1 that were holding you back the most.

    The RPM Limit P.I.D also could have been affecting it to. It was for me on my 06.
