raising shift point gains??? how much time or mph am i looking to gain from raising the shiftpoints from 6200 to 6600?? I have 228R - ls6 intake - lt's - 4.11's - 3800 verter and few other bolt-ons i run 103 on motor and 112 on N2O its still pulling hard at 6200 so i want to raise it up some. i feel as if it should be around 105 on motor.

Stock trans,6800 rpm shifts!!!!!!!Did you get a dyno tune on the motor/jug.You need to know where your hp&tq peak,and adjust from there.

no, i went to have it tuned and the guy had a TT WS6 blow a tranny on the dyno and it was sitting there so i couldnt use it. but from all these graphs ive been looking at with the same cam and intake, they all run up to 6400 - 6500 then flatline and most of the time shifting at 6600 - 6700. I know its still pulling HARD at 6200 in mine right now

Try 6500 -6600 then go to the track,see if its picked up at all.
It took me a couple of times screwing with the shift points to get it right.
Well worth the time and effort.

you'll see an improvement, prob nothing to serious, but noticable. however; stock autos will hold lots of power with the stock shift points, but if you raise the rpms you will kill the tranny extremely fast.

stock tranny here too.... in a heavy truck, but only at 6200 bout to be 6600 maybe today when the retune from nelson comes in. I have tranny cooler, vette servo, billet 4th servo, and HD-2 shift kit but with a BIG 3800 converter my gauge doesnt move much its usually around 125 - 140 when crusing and maybe 160 - 170 at the track

Been runnin those shift points and cam for around 2.5- 3 years now.
One of the first mods was a shift kit,tranny cooler,verter.I change my fluid yearly,even if it doesnt look bad.
