What you think?

 

what trans and gears do you have?

 

m6 3.42

 

seems kinda low. i made 420/395. with an MS4 fast92/PTM 92 and stock 853 heads. prob just the dyno though. many people dont know that chassis and engine dynos are actually used for disappointing people that just pent a bunch of money on their cars. numbers dont matter. how does it feel? got any vids?

 

Yeah I was hoping for 450hp as it seemed so many people were getting that no prob with that setup. I am pretty happy with the torque though. It pulls very very hard. traction is def an issue. Im happy with it so I guess thats all that really matters.

 

long as you're happy. you do the install?

 

of course def was a rewarding project. I was just happy it ran let alone put down the numbers it did.

 

ha ha that was good for a laugh.
i do all my own stunts errr uh work too
just ordered my buddies TSP tsunami
cam and other misc crap to put new lifters
in it.

post up a vid of the traction issues... maybe we can
help diagnose that problem....

 

lol yeah thats how feel too. As far as traction goes im thinking its just my stock suspension with that amount of power is not gonna cut it. I have nitto DR but they have about 12k miles on them so im sure there about done. Next mods are full suspension inc a 9 inch and a new clutch.

 

do a FAST intake and i think youll see some great gains.

 

Thats a really nice curve. Screw the peak #'s. It makes 400+hp from 5200-6700rpm.

 

Looks good!

 

I agree with Slowhawk, looks like a great curve! Should run really well at the track.

 

if the red line on the air/fuel graph indicates 13.1 AF, then is looks real lean, especially up top

 

Prolly the LS6 intake holding back a couple horses.

 

"if the red line on the air/fuel graph indicates 13.1 AF, then is looks real lean, especially up top"

Exactly what I was thinking.

 

So what should I tell my tuner? The car is running pretty rough. By rough I mean it back fires at high rpms and the car feels like it shutters real bad. Also when pulling out in first gear the car feels like it lugs really bad then kind of comes alive at about 2500 rpms...

 

Just curious, do you have an aftermarket fuel pump? If not do you feel you have the need for one? I've got H/C/I and wondering if I should install one.

 

No I do not. Im not really sure if I need one or not. Never really thought about it actually.

 

I'm not up with what an F/Body fuel pump flows but with the power you're now making it will be a wise choice to upgrade.
