Kind of hard to compare the two graphs seeing how the stock graph show rpms across the bottom and the cammed graph shows mph...

Guess we have to a little rpm to gear matching to compare the two curves...
Tech too lazy to hook up the tach signal.

I'd look into the degreeing and the tune, your A/Fs don't really look ideal in the "after", you may be able to play with the timing to get more down low.

EDIT, nevermind about the fuel, I just saw the rich curve was a N02 pull.

Stock lifters? What is your lifter preload? How did you calculate pushrod length? How much advance is ground into the cam? Timing chain used? IMO you are pixxing in the wind w/o degreeing the cam and checking lifter pre-load.

Default Update Update

UPDATE UPDATE. 08/18/2005
I advanced the Cam 4º like COMP said,with an SLP doble roller Adjustable chain also added Jet Hots LTs, 3" Xpipe and ported TB.

Well after all the installs I have to say I am so FUCKIIIIING happy, the torque and throtle response is unbelibable, just wow, the whole combo between the advance of the cam, the LTs and Xpipe and the TB.
The car is running sweet, its so sweet i haven`t even wanted to use the No2.
Thanks god everything came out perfect. Thanks again to all that helped.
SVO #36s are going in this weekend.
Here is a little video of the whole thing. Haven`t dynoed it yet.
