dyno'd today
We have similar setups, and your tq curve actually looks fairly similar to mine, with a dip in that one area.
This is through 4.10's and very heavy wheels as well, heads/cam in sig.

what did TEA do to the heads? take the out of the box 205 and run there Judson port through it? any delta from before and after?
also can you post up all your previous dynographs and setups? you did previously run a PP ls6 style combo right, then picked up ~18rwhp or something with the out the box 205's unmilled with less compression then the PP's.
from what i remember your car has never been a dyno queen so it doesnt suprise me you didnt hit 450rwhp even with every concievable bolt on. im more curious of the overall power curves of your 3 setups then peak hp/tq.
as far as tuning Don knows what he's doing, and magnaflow cats flow quite well.
probaby could of made the same power with the old combo and just milled the 205's, run the cometics, and kept the FM11...

don has all my graphs on his computer at work. maybe i can get him to put them up
TEA ran there stage 2.5 program through the heads
car is not running that great now even after the tune. i hope the idle relearns itself. im stalling at every light

Damn man, I don't know what to say. I've been looking forward to you dyno numbers for a while now, and I'm probably as let down as you are over them. I think retarding the cam some would help the numbers.. but still, you are 20rwhp or so away from what I was expecting. Keep us updated.
If you're stalling at every light, I'd go to another tuner for a secod opinion. Slowhawk is a good tuner, but he's tuned your car twice with less than stellar results, the A/F is way off, and it doesn't idle correctly. I'd give another tuner a try, just to have a second set of eyes look it over.

Where did your tuner set the idle at?
I know they can adjust the t-body w/ LS edit but I swear by the drilling the hole method. It just flat out works perfect, it keeps your idle down too (mine is @ 850) it was my best mod to date as far as an improvement over the stalling I encountered after I did my cam/headers. Also could it be the N/W in conjunction with your combo? I know they are thee best C5 T-body but many T-body porters have difficulty with the C5 T-body. Also what about the FAST intake is it possible it is allowing umetered air due to poor fitiment ?
(I would gamble that if you switched back the the LS6 Intake & a shaner or stock t-body you would run better and post better numbers -- just a hunch based on your current numbers)

Maybe the rocker arms are costing you some stuff. Aren't they heavy. Your pre-load might be off on the lifters. I don't really know I'm just throwing some ideas out there. I cannot possibly see how you aren't making over 450rwhp. I've always wondered what's been up with your car, cause it has never put the numbers out that it should. If I were you I would go down from the basics and check EVERYTHING. You've spent far too much money, time, and energy to only get the numbers you are getting.
Yikes, I'm running a 346 with a comp xer 228/230, mildly ported ls6 heads, fast 90 and dynatech LT's, HS 1.7's, stock w.p., and stock pulley, 4.10 m6 and put down 443 rwhp/405rwt with zero driveability issues. Sounds like you may have some tuner issues looking at your A/F.

im at 3/4 turn at zero lash
That is exactly where I am at with the factory rockers....

That graph is a street type setup which is needed when ussing a Vararam setup and I fully track tested.
We made alot of pulls that day varying timing/A/F across the board.The A/F was at 13-1 across on many pulls.Timing was varied from 22-30 degree's with very similar results.Which means that is all the combo would make OR there is a restriction somewhere which I would point towards the exhaust setup
Keep in mind my dyno is not forgiving on dyno #'s and I DO NOT fluff them
His car sit's to run a very low 11 on street tires.

Also,if the car is still stalling,there can possibly be a problem in the setup causing this.The car has been having idle problems since the last baby Cam too.The setup is very mild and should be holding the idle tune

i do not understand why everyone is upset with those numbers? there are cats in the car. I would expect a hella lot more w/ the cats removed than the 5-10 hp that some have said. Hell, i say possibly 15-20.
