SQive

For those in the DFW area, there is someone local that can custom tune your ZF8 TCU. I just had him do my SQ5 and I have to totally agree with what others have said; it's like going from stock to stage II all over again! There is a torque limiter that is turned up, stall speed, AMax counter, and of course, shift points. I had my stall speed turned up to 2800 RPM, my AMax set to 2,000, and my shift points set at 7,000 RPM. OMG. . .I can't believe how much more power there is without doing anything to the engine! We turned the auto-upshift in manual back on and it all works beautifully. I highly recommend John and this TCU tune was worth every penny. PM me if you need his contact info.
