hows this dyno run the car is pretty much stock except for a airbox with k&n filter, random tech exhaust, qtp cutout, and hypertech settings.
if u cant see from the picture. it ran 303.55power 328.47 torque with the cutout out closed.
with the cutout open it ran a 305.33power, 334.49 torque
hows this for a stock car, was it a decent run??????????

Well, to be honest, it appears your HP is a little low.
I have owned 3 LS1's ('99-00) and with a lid, K&N and LM (which is equivilant to a cut out) all dynoed over 320 RWHP and 333 RWTQ, on a dynoJet
While some would say that your A/F is good, IMO it's a little high/lean. Keep in mind that when a car is on the dyno the A/F reading that you see will lean out when you drive it on the road - reason resistance.....dyno roller has very little resistance and concrete creates a lot.
A good A/F ratio for a dyno reading is anywhere from 12.6 - 12.9...again that's my opinion.
As for what's pulling your HP down - I can't tell. Your torque is right where it should be, so that adds to the confusion.
....could just be from the dyno calibration.

Also ever dyno is different. What u get there will differ at a different dyno. I think ur numbers are good. U maid 4 more hp than i did. before i put the headers on that is. Also u might wanna take off the programmer. I had it and it sucked.
