Need help setting WOT 1-2 shift

[12secformula]

I added a Trans Go shift kit to my car, now it short shifts on the 1-2 shift at 5700 RPM @ 39MPH. It is programmed to shift at 36mph & 6000 on the 1-2. It is exceeding the MPH, but not reaching the RPM? The 2-3 shift is fine. Should I start changing the RPM or the MPH to dial in the shift?

12secformula,

Welcome to the forum. :cheers:

You could try either of these:
a. raise the RPM a few 100 and see if it shifts higher, or...
b. raise the MPH a few and see if it shifts higher;

Thanks for the info and the warm welcome! :cheers: I set the upshift at 39MPH and it shifts right where I want it to.
