He wants stock dyno slips. 
I have one, I have to find it though. My hp and torque were pretty nice, peak numbers were 338.6/351.8 with 160k+ miles on a dynojet, just a few ponies less on a dyno dynamics (337 RWHP @ 5650 rpm's
339 RWTQ @ 3250 rpm's). I will try to get my dynojet sheet scanned tomorrow.
NOTE - the graphs on each side are on a different scale
The car last dyno'd 309/304 with full bolt-ons, th400 w/4000 stall on a dyno that showed 30hp less then the dynojet listed above.

[/IMG] I compared your stock dyno to my stock dyno. Both are dynojets at same latitude (Houston vs. Baton Rouge) and pretty close temps. Here are the differences..

So I think my sig is right. My car is down on power. It doesn't look like I need the driver mod after all.

ddd One more interesting mathematical fact... Your car is accelerating faster than mine. In other words, not only are the absolute HP numbers higher @ each rpm but the slope of your curve is steeper below 5250 than mine and flatter above 5250 than mine.

My curve visually is a straight line from 3500-5000, whereas yours is concave over that same interval.

Keep in mind tee-boy I have an '02 which has better heads and a LS6 intake from the factory so it will have higher numbers.
If you still have the LS1 intake that is stock on the '98 replacing that with a LS6 intake will pick up lots of power on the top end.
Dumping that slowmaster for another catback or getting a cutout will help as well if you like the sound of the flowmaster.
