Any idea what your race weight is? Could be a pig heavy car.....
Start with getting rid of that handheld tuner. 101 mph is insanely low for a ls1 m6. Any idea what year ls1 went into the car? I'm willing to be a 98.

1st!!
check and make sure that the throttle body is opening all the way at WOT, it may sound rediculous, but i drove my Z around that way for years without knowing, just thought my car was a dud ls1, and when i found this issue, man was i wrong, easy 60-70 hp left on thetable.

i got the car dynoed today and it put out 260/330.... the car is losing fuel pressure past 4k rpms. I have an appointment to remove the fuel pump booster from when it was procharged. we believe that that is the problem.

No love for the superchips tune? The superchips tune work very well, at least for my GTO. Good luck with the dyno tune

Tune is junk, that needs to go. Get the car on the dyno, see what it's making. If it's low, like in the 290's or something, leakdown/compression check, I'll bet #7 is shot from the procharger, procharger setups kill #7 faster then anything, always have (constant boost no matter what condition just beats the #7 piston to death)
What does the car weigh? I see you have a bunch of stereo junk in the car, that never helps ET Rip that ricer crap out and give it the heave, that will probably help

Ouch, that sounds about 80rwhp too low for those mods. What kinda dyno was it?
