    Probably won't work on your 2007 for the reasons iCanuk explains in that thread. Only thing alfa can do for you is probably throttle relearn if that is what is causing the lightening bolt on the dash to light up.

    I have done throttle relearn still same issue. I been looking at other trans tune maps on here and limp mode rpm is set higher at 1k instead of 500 like I have will try copy and paste a trans tune from on here and see what happens.
