What drivability issues are you having? Mine won't idle good cold! It wants to idle fast around 1500 rpm, but after it warms up it idles fine. That and some shifting at low speed problems is really all the problems I have. The only tune I have is a Hypertech Power Tune. I am still waitng on HPTuners for 98 models
I have all those same problems. My engine is conpletly stock. Yank SS380 converter and Hypertech here also.

But your graph holds a steady line of well over 300 rwtq from 2-3k rpm. That is more than peak tq of a stock ls1!
Umm...my car had 330 peak torque stock...just a hair under 300 RWTQ at 2000 RPMs...perhaps that is what you were referring to...

I had the same issues. After stressing for a few months I ended up witha 7/32 hole in the t-body. Car then ran perfectley should have done it sooner.
Good numbers....Long primary tubes and merge collectors = Torque.
