Where's the graphs???
Oh yeah, congrats.

Just playing, that sounds awesome though I have to cast doubt on the larger injectors and MAF making a whole lot more power if the air fuel was never leaner than 12.5:1. I would guess with the 3L manifold your torque was on a downslope anyway by 6500 rpm.
Still, if you were able to make 300 wHP with 24# injectors and stock MAF, then I once again pose the question of:
WHY THE F'in HELL people are looking to slap 42#'rs in their cars????

What cams are you using, SVT or 3L stock?
The graphs will really tell me alot more so I will wait for the torque curve to say more.
