PP ls6 heads and ms3 I made 410 hp and 371 tq, 4:10s and 2001 m6 , underdrive pulley, started at 393 from first pull and got all the way up to 410 after a twenty minute shutdown. This was just a dyno pull as i had my ecm sent off to TSP for a mail order tune.
I had TSP tune the car for nitrous, so I imagine they pulled alot of timeing and also have it running rich. Throughout the pull the car smoked alot (unburned fuel) i suppouse. Clutch is also slipping at high rpms ( just a little ) I can smell it.
I will try and post a pic, or get someone to help me.
This all was on a dynojet, at 105-106F (average temp here is 100 and the shop has know air) temps and 9% humidity.
What do you guys think?

Yea, I agree with both. Tsp said before I got the tune I should be around 410-420.
I had the cutouts still on (not open) and their was auto 427 2001 ss on the dyno before me that literally picked up 20hp and 30lbs of tq with his cutouts open and with stock cats.
Also like I said, the "mail order tune" was tuned for nitrous and some of the timing had to back out and I know for a fact that it was running pig rich.
I will be gettng it tuned for N.A. form shortly.

yea that is true. What numbers am I suppoused to be making? Most head and cam cars do about 400-450 right, and most of the higher end have aftermarket intakes and dyno tunes? Well at 410 I believe that I can find 40 horses. I am going to do a couple of more free things and get back on the dyno to see what happens.

Once you get the new NA tune in there and it isnt running so rich you should pick up about 10 or so rwhp. Then if you throw in a fast 90/90 combo you should hit around 430+ rwhp, which is pretty damn good. Also, without your clutch slipping you will see higher numbers as someone already said above. Its difficult though to compare Dyno numbers online as some are corrected and some arent so they will be higher. Plus, you need to look at a comparable type of dyno (dynapack/mustang/dyno jet/etc) and even then the same type of dyno might register higher than another. Look at my sig. I made 370 rwhp on a 232/238 cam on a 112 lsa and .640/.610 lift, while other people say they have made over 400 rwhp cam only with smaller cams than I have.
