HP is on it's way... I am working on a 55 BelAir with the engine and transmission from an 06 GTO. Two problems the car currently has: One, it doesn't seem to have a rev. limiter (I can send you the video) and two, the transmission does a quick shift when WOT around 20 MPH. Transmission hits 1st for a fraction of a second then immediately to second when it should be winding out in 1st and shifting about 200 rpm below the limiter to 2nd. It shifts from 2nd to 3rd @ 6500 rpm so the problem is just with the 1-2 upshift. I have programmed a 4L65E with the Supermatic TCU software from GM Performance (1960 Corvette w/ LS3-4L65E), so I am quite familiar with proper transmission settings. I am hoping the HP software can help me solve both of these issues. Anyone? Thanks in advance.
