A4 shift at when in 4th at WOT? my old '98 T/A with 2:73's shifted between 5800-6000 but for some reason my '99 SS with 3:23's(of course)shifts at 5500-5700 is it just the tach lagging behind??? I hope this will not hurt my ET's????? <img src="gr_images/icons/mad.gif" border="0">

 

It should shift at 6000. Sometimes they don't; sometimes its the the tach. Do some WOT passes and ATAP only your rpms and see where it shifts.

 

I looked at some old ATAP logs and mine shifts at 5800-5850 with stock shift points.

 

it will not be a problem because you won't go out of third in the 1/4 mile..

 

All the stock tachs are slow...

 

TTT!

 

My 98 Vette A4 shifts at 6400, but maybe when Ed Wright programmed my PCM he set it that way.
