Shiftnoid
I ran a shiftnoid for years with no problems once I got everything setup right. Shiftnoid has a great tech support and they can help you find the problem. If I had a 7000 chip in mine, it hit hard right at 7000 and if it doesn't then something is wrong with the setup. I ran a turbo 400 and it never missed a beat. I would call shiftnoid and they will walk you through every step and have you test it as you go.
