Well i drove my car 2 1/2 hours away to get tuned and was a bit disappointed. He couldn't get anymore power over the stock 99 tune. I dyno'd 338hp and 346 torque??? I was expecting more like 350 hp range but was way off...any ideas? Perhaps am i just expecting too much??? Mods are in sig any and all help or ideas appreciated.

Not trying to disipoint you but it looks about right to me, you have headers, LS6 intake, throttle body bypass and a ported throttle body. Bone stock is in the 285 to 310 rwhp with any tune (stock or tuned) and with the those mods thats about what it would give. Congradulations nothing to be dissapointed with.

nothing to be dissapointed about. my bolt-on car put down 332 rwhp. Those are good numbers.

all dynos are not created equal. the best way to compare your car is hit a car club dyno day. then you'll know how yours stacks up. my dyno #s suck but my car runs great.

Is it possible to not gain any power from a tune? I also just drag raced my car and lost 5 mph and the only major mod i added were the headers...could these be causing a power loss and no gain from tuning?

the headers will most likely give you a bit less low-end torque, but the WILL gain HP up top, the 2.5" y pipe isn't helping though...you have huge headers and a small y. That would be the weak link, as far as exhaust. The HP#s seem pretty good though, i would think a tune woulda helped though...just think, even stock cars benefit from a tune...thats why they make Hypertech programers and stuff

Sorry if I missed it but what was the a/f at and was timing added? Oem tunes tend to run on the rich side and timing is conservative.

Nothing to be dissappointed about, my 2002 SS 6speed dyno'd 339rwhp stock right after my brothers 98 Auto Formula dyno'd 350rwhp! I dont believe these numbers necessarily but it was definately lower than a bolt on car! I was about 65 degrees with zero humidity though!

Don't forget sometimes the dyno's correct down on great air day's.. avg lsx bolt on car 98-02 is anywhere between 325-365rwhp depending on A4/M6 and various intakes' and bolt on's... not all lsx's are created equal.. the 6.0l Ls2's are even worse.. had a bolt on one dyno 352 and a bone stock one do 5 more.. lot's of variables.. especially the condition of the ignition sys, fuel sys, etc...

unless you did a stock baseline run on the same dyno, it's hard to know how much you gained.

For me, before exhaust, I pulled 306HP, after headers, true duals and ported throttle body, I went to 349HP. On the same dyno.

He's not running a catback or anything, just dumped after the y. I bet you don't have enough back pressure, I'd get a bullet welded up, at the least should give you a little more back pressure and help a bit. Also, does the car feel faster??? I know when I was bolt-ons and got it tuned it put out 335/348, but the car puller harder through the entire RPM range.

Here is the run down on the dyno my IAT's were @ 82.1F using an SAE correction factor. The barometric pressure was @ 28.82in.hg. The AFRs were 13-13.5 range

Nothing to be disappointed about, seems right on. Do as another said and go to a club dyno day. That's what I did and my friends said my car put out good numbers for only LTs, O/R Y, CB, QTP ECO, Lid and FTRA through an A4 untuned

Good numbers for 2 items. Instal a cam and it will complete it and you'll be in the upper 380HP+ depending on the cam. Good Luck

looks normal to me.

Looks normal to me too.Not gaining anything over the stock tune can be misleading. I find with todays gas quality that all these cars have too much timing from the factory.Every car I've seen has had KR.On the dyno the KR won't be as present due to the lower load of the dyno.Most tunes I knock out 3-5 degree's of timing.The end affect is even though the car dyno'd the same hp,they run consistantly faster at the track.
