    i agree, seems low, but we don't know any other mods you might have...

    first off what stage of the Patriot Ls6 ported heads? I have the Stage II heads from them and a smaller cam (Comp224). check out my sig for results...

    that kind worries me because I want to go to a bigger cam (Torquer v.2) for more TQ, though I will take the extra HP gains as well...hehehe

    i also have slpLT,high flow cats, 3in y-pipe, 80mm BBK TB, slp lid K&N air filter, 3.73's, Stock MAF, with a tune. when they tuned my car they said that i need a new battery. he told that because of that my idle was going to be off. he said to come back when i get one and he will fix it. could that be part of it. it seem to be running lean. thanks for the input.

    the cats are taking away about 5 rwhp and it still needs a retune from what you say.
    you should be around 410 when tuned.

    You gotta either have a bad tune or something wrong with that car. I would think you should be close to 450 or so. Hell people putting down 400+ cam alone.

    Stick, or automatic? A4 numbers sound pretty close and a little low for a M6. I made 436rwhp/420rwtq with a 234/236 nitrous cam and some decent CNC 5.7 heads. What supporting mods do you have?

    what were your dyno numbers prior to the H/C?
    what kind of dyno?
    what kind of dyno shop? (hole in the wall? or high tech race shop)?
    what is the milage on the car?

    how does the car feal?

    dont get hung up on the numbers.... they dont mean much.
    if you baseline was 315rwhp and you are using the same dyno then an 80rwhp gain is OK.... many dyno's are not calibrated correctly, and many seem to put out odd numbers from time to time.

    does the car run like it should? ..... should pull really hard around 3K and up?

    and one more thing i forgot i have 36lbh bosh injectors. it is a M6. my mileage sucks, its right around 16mpg 50/50 city/freeway. before i did this work they did a dyno run and they got 323rwhp with headers. i am also going to take off my cats and have it retuned. but i took it to the track last night and i had a hard time getting it to hook up. my first run was 13.147 at 111mph. my second was 13.128 at 109mph. my 3rd was 13.470 at 113. and my last run i had a 2.035 60ft and then i missed 4th and still ran a 12.770 at 105mph. then it started to rain. took awhile to get used to the new clutch. my first 3 runs sucked but i was happy with my last. i am going to get some slicks this week and go back. the car feels stock till about 3000rpm after that it pulls hard untill 6500rpm. i am going to get it retuned and we will see what happens. thanks for all the input.

    Your mph seems a little low even for the #s you put down. I'd get someone else to look at the tune.

    do you have the stock 10 bolt? if so I wouldnt go any stickier than drag radials but they should still help you alot. You really need a 12 bolt though to get the most out of that cam. Being an M6 car you would have to drop that clutch from around 3500-4000 for a good launch but be able to stick it. Those cam specs would have been great for a stalled a4

    Uhh nope, not many reach that level unless they go absolutely wild with the Cam and have full bolt-ons.

    Also remember A4s lose a lot of numbers especially if they have a higher stall TC in them.

    For instance my wifes car NA puts down 440rwhp/385rwtq through a 3400 stall. Her combo is AS Stage II heads, ECS cam (exact specs unknown based on vaccuum and tuning somewhere in the ~240 range on a ~112-113 LSA), FAST 90/90 (unported), and full bolt-ons. I would expect another 20-30 with a T56 behind it.

    Uhh thought he said M6? Look 4 post up. If he was an A4 I would agree that is about where he should be. Also since he does not have a "wild" cam in there I would think he can do better than 16 mpg. I think his tune has a little more that can be worked.

    ok well i still havent been back to have it retuned but i did got back to the track. and what a difference. i guess it needed some time to break in. My best time was 12.7 at 112.7mph. i still need to get some drag radials and most likely a new rear end but we'll start will the tires. thanks for all the input.
