    I have updated everything. Later today I am going to start from scratch, and load the original tune in my truck, and make it into a COS. I will post back with the outcome.

    Well I installed the newest EFI Live versions, and it still goes into REP. The only thing the update did for me was make the program go into Demo mode when I open a tune without the Flashscan plugged into my laptop.

    If you want to try one more thing,Put a bigger pulley on and lower the boost and see if it goes into REP.Other than that,You probably have to go to a cable TB.

    I didn't get it as much before I increased the boost. I want to try a few more things tomorrow. I built a divider that lined straight up with the blade when it was WOT, and that didn't help. I would like to apply vacuum to the TB tomorrow and see if I can get it to trip. I just can't understand why turbo guys don't get it, and they move much more air than I am. On performancetrucks.net people stated they had this problem, and switching to a Nick Williams 102mm TB resolved their issue, so it has to be something strictly with the TB.

    Thats what I have on the vette,A NW102mm TB.I ran the car a few times at 100% throttle,But only about 10# of boost and it ran fine.Soooooooo maybe you have to get your self a NW TB before you pull your hair out

    Just to update everyone, I figured the problem out. I ended up getting an LS2 throttle body and it cured the problem. The air entering the inlet pipe was working like an airplane wing, and lifted the back of the blade up. That was forcing the blade closed, and causing REP. The throttle body opens in the opposite direction, therefore the air entering was forcing the blade opened. My logs showed that the TPS was rock steady. I would have loved to try flipping the throttle body to see if it had the same effect, but I didn't have the room.

    C3904 and C3905 need to be put back to stock or the the TPS tests are going to run all the time rather than just under steady state conditions(55-65kPa).
