Default Read these 2 dyno sheets please


2001 SS M6w/ SLP LT's, Hooker Catback, Granatelli MAF, BBK TB, "Free Mods" Whisper Lid, K&N, SLP New Smooth bellows, HPP3

http://memimage.cardomain.net/member...2_144_full.jpg
2001 Z28 M6 MTI Lid, Old SLP bellows, ported stock MAF, HPP3, bump stop mod, powershot filter, "Free Mods", Flowmaster on other ALL stock exhaust


I was looking at the A/R on the SS and it seems it varies quite a bit from mine. Anyone know whats up with that, it goes from 10:1 to almost 14:1 between the 3 pulls
whereas on the Z28, its damn near the same on all 3 pulls. Also, can anyone tell me why the Z28 is only 15HP less than the SS with the LT's, catback, and BBK?

Thanks for the input!!!

some of us dont know the answers to all of the 'real' questions
but ive always been told to stick with the stock maf, and ive only heard bad things about aftermarket ones. i would do what you originally said and switch them with a stocker. who knows? it only takes 2 mins to do and could solve all the problems

All I know is what 99formula said, doing anything but descreening the MAF is taboo around here. Too many people have problems.

GMAF has to be tweaked to report the current airflow to the PCM, since it is a larger diameter than stock. Since the Maf Hertz and the g/sec table is not a linear graph, the Gmaf can only be close at certain levels and will usually be farther off the higher the flow.

I have never seen good dyno results with the BBK, all of them with only the BBK being the variable has shown a loss. It's an 80mm throttle body, but the intake manifold opening is only 78mm, unless you are using one of the F.A.S.T. 90mm units, but you did not have that listed.

maybe long term fuel trim. i say that because the first was richer, the second leaner, and the last in the middle. does the car see alot of WOT use?
