Warning!: Contains low dyno results Ok guys i have a 01 m6 z28 with longtube pacesetters, slp lid, a piece of crap ported maf (cracked), ls6 intake ,241 heads, smooth bellow, 323 gears with (no tune), ngk tr55 plugs and msd wires ..
I went to g force and mike said my maf was probably the reason .. Anyone else could throw some reasons .. i had a oil change about 1600 miles ago and sparks about 2 months ago..
also i just went to a junk yard and got a 99 corvette maf that doesnt seem to want to go into my slp lid.. should i try harder or return it ?

A bad/dirty MAF can make your car feel like its 30 years old. Mine would cut out real bad and not idle very well. Unplug it and see how it runs. Now that I look at the MAF you need to trash that thing and get a stock one!!
My car made 355/370 with bolt ons and when the MAF went out I was getting pulled by a stock TA with a cat back. Unplugged the MAF and raped him. If you look at the graph down low the numbers are about par then up top something is happening. My $$ is with the MAF like they said.

the a/f wasnt included but i checked all the wires the last time i changed the plugs they where all still in great condition. ive had bad plugs in the past on previous cars ... i dont thing its the plugs
I have a vette maf I had to smooth out the inside of my slp lid to make it fit. And wd40 to slide in better ha. Also your torque looks correct and the peak horsepower looks like it peaks about 400-500 rpm early...
He doesn't have a tuner, but they weren't logging AFR so it still might not have answer any questions.
I agree with most everyone else to just unplug the MAF and see if it runs any better.
I also just dynoed my car with a cracked spark plug and lost about 70rwhp. And the car really didn't run that bad.

Why would anyone dyno a car and not chart the A/F? How do thy know if it's too lean? You NEED to know if it's too lean so you can get out of the throttle if it is.
That thing peaks at 5K and then nose dives. It's possible it's dangerously lean. That or bad valve springs, or severe knock retard.
