Do 98s have torque management?

I just installed a 3500 stall and my 1-2 shift is horrible!!! the engine compleatly cuts out for about 1 second. also it hits the rev limiter on the 2-3 shift. I am not happy because I like driving my Camaro every day but it is not fun driving like that so I am stuck driving my beater car. I am getting it tuned next month with the cam install

My TM has been deleted but don't see why mmy trans life would be shortened all that much, it shifts exactly like stock programming except at WOT 
We left the trans pressure the same, lowered all shift times conservatively to .300 and left 3-4 alone(stock settings because 3-4 is weak), set the Max engine tq to 500, don't think i make that much just yet

Decrease shift adaptation times to lessen
the duration of the power cut. Increase
the torque level for reduction to occur, and
change the reduction percent to suit your
preference (I currently try and limit input
torque to 400lb-ft as a compromise between
performance and protection). This affects
WOT and near-WOT but leaves most of my
part-pedal driving alone.

I was pulling up to 25 degrees of timing during shifts. untuned +23 to -4 during shift on A tap.
When people say they deleted TM, they don't mean they pushed the TM delete key and that was it. Its a series of tables you can either replace all the numbers with 0's or lessen the TM effect.
TaJay. TM controls max TQ input, reduces timing during shifts, and controls shift times.

leave TM tables alone IMO. Don't mess with shift times either as that really seems to screw things up on the 2-3.
All you have to do is work with one table. In the IGN parameters is a table called SPARK RETARD LIMIT. In the 98's it is set to -10 degrees. During a shift with TM enabled, it will pull timing back to -10 degrees which can be up to a 40 degree retard if your running 30' peak adavnce. This is how it effectively shuts off the motor.
You can adjust this figure to dial in your power during shifts. Set it at something like 24 degrees and you'll get full power shifts. Set it at 10 and it'll kill some power but not all. Adjust it until you get a shift you like. This table also effects max Knock retard so don't set it to equal your timing table. Keep it 4 to 6 degrees less than your max timing.
If your monitoring it with a scanner, the shift retard happens fast and the scanners frame update rate will not always catch it.

My shift times on 1-2 and 2-3 are .300, fairly conservative. I left the 3-4 shift times stock. .450 I believe. These changes are not really noticable at part throttle. If you kicking your foot around on and off the gas its a bit more responsive, other than that it just effects my WOT performace.
