You certainly gained a bunch of power in the low and mid-range. You'll have to refresh my memory of the cam specs. I only have cams listed by the user's name and not internet screen name.

those m6 numbers do seem low but maybe you need some new heads but since you have a vengence 92 they will open the tb snout too 100mm for not too much$ you could sell your tb to get the new 100mm that will defently pick up some power

The car is sick in the low and mid range the customer love it but I thought the peak power will a little more.

Why does your a/f ratio look like a roller coaster? I wouldn't doubt if you were getting some detonation since you are tapping 14:1 at some points.

I agree on the posible detonation. Maybe some timing is being pulled out.

The air temp was a bit higher in the second graph (almost 16* F)

LOOOOOOOL I swear man thats the same thing I told the tuner roller coaster I dont know much about tunning but the A/F looks like crap.

This is not my car I just order parts from U.S to overseas




He pulled two degres if I remember correctly.




Thats right the wheather was hot as hell (overseas)

Oh the car had only 80miles I talked to the owner last night and he said the car feels a lot stronger after the 300miles so we are taking the car back to the dyno in the next two weeks to see the new N/A numbers and Nitrous numbers

venom ws7

But I need more help and advice what should I do next time on the dyno????

Timing??? A/F??? best shift point????

One last thing Patrick the car SOUNDS SICK and pulls hard all the way past 6600rpm.

You could try to talk to jerry formato. He is one of the best LSX tuners out there from what I have read and you could talk to vengeance because everycar they tune leaves with a happy customer and good #s.

Believe me if it was easy to let one of these guys to tune the car I would call them ASAP.

But the car is Overseas the wheather , Fule is very diffrent.

I don't see a whole lot of changes that could account for a big horespower jump that you seem to be looking for. It is hard to comparre A4 to M6 numbers anyways. If it feels strong, then go with it. There is probably nothing wrong with it. Most of the setups making 500 have AFR, TFS or ETP heads.

Whats the engine size? I see it has an Eagle crank, but is it a 403 now?
First thing I would do is make sure its hittin on all 8, then get the A/F in line, then hope for the best.

Yeah thats true but you can always ask for a little advice from them, its always worth a shot and good luck bro. Since im in kuwait right now do you know when the sandstorms start? I ask because today was windy but not like a real sandstorm well good luck bro.

That power change isnt very suprising, you picked up 26 peak but also picked up a good amount throughout the range. The cam change was not drastic either. How you expected to pick up like 50HP from a minor cam change and intake I dont know.

1ORANGEWS6

He changed more than just the cam. A better intake and bigger headers. I'm not and engine expert but I would have thought it would have picked up more than what it did and going to an M6 from an A4 tranny as well.

It will only pick up that kind of HP and tq if there was something wrong with the setup. If it was deficient in some way.
Going from an A4 to an M6, if you're running the A4 locked, makes little difference.
Now, back to my original question, is it a 403? If it is, its pretty weak. Before or after the latest mods.
Now, if the compressions off, if theres a bottleneck thats causing a restriction at higher rpms, then theres your reason. Theres ways of diagnosing these problems too, but it needs to be in the hands of someone with that capability.

Heads? put some TFS or AFR

Its either 402ci or 408ci I'm really not sure.
Thanks for the advice man I'll let you know the new numbers.



Better and bigger cam.
from stock LS6 Intake and stock TB to PORTED 92mm FAST Intake/ 92mm TB.
crappy headers to 1 7/8 Headers with 3inch off road X-pipe.
Manual transmisstion and one piece shaft and light aluminum flywheel

all these mods only get 20rwhp peak power is low IMO



Thanks for the replies guys.
