I am new here on this forum however some of you guys I know of other forums (small world huh)
I am from The Netherlands and drive a '91 454SS with the stock 4L80E controlled by the stock 16147060...

I doug up this old threat just to know if you where able to set the performance mode to 0 on the 16147060 4L80E program.
