I have a Slp predator...im having trouble with the transmission shifting to early on the 1-2 shift at WOT... it begins to shift at 5300rpm and completes the shift at 5600rpm...im stumped on how to get it to shift right around 6000rpm to be able to use the extra power...any help would be appreciated because im going to the track this saturday and need to figure this out....Thanks!

Does it shift the same way with the stock tune?

Have you tried raising the WOT shift points?

it has the modified stock tune in it...the shift rpm is set to 6000rpm and the mph i tried adjusting but that had no affect... im at a loss at why its shifting so early?

is the computer shifting it earlt because the first gear is so low is 4l60e transmissions?

With the modify stock tuneit will shift at the same time as the stock tune unless you change it...have you confirmed where it shifts with the stock tune installed?

Have you tried logging it to make sure it is not a slow tach issue?
