I'm at 3" MAF, but unfortunately when I first added it I also installed a pop charger that day. Best comparison I can offer is V+ + pop charger= 242hp/216tq (very first tune); V+ + 1/2" spacer + '06 airbox= 261/239 (most recent & 3rd tune). Too many variables between dynos to determine gains. But just adding a 1/2" spacer shouldn't see gains like that. So IMO, I think having the 3" MAF really takes advantage of getting just that little bit more air in the intake.

Oooh quite nice! 18hp and 23tq with no exhaust bits. I know it's on different days, but still quite nice. I'd like too do a 3.5 with a larger tb. But that's only if the tax man is nice, or If nothing comes up.

I can't eat to see how the hr responds to the 3". It might give me more reasons to be jealous.

Oh sorry, I've got full exhaust: crawford headers, Z1 HFCs, and Invidia Gemini TD. Just between those two dynos, the only differences were the pop charger to 1/2" spacer & '06 box. First dyno tune was like July 2012, then this most recent was a couple weeks ago.

And I've thought about the larger TB, just can't seem to justify that purchase just yet....ya ya, among my other purchase I might as well

I say peak gain of 7hp, while gaining 3-5hp across the power band. And a gain of maybe 5tq.

Will be doing a baseline with the Stillen Gen2 Intakes right when we get there, install 3" intakes, and let Bobby tune it, then will have final #s.

- and as i said in my earlier post, I hit 303whp and 272ft lbs with the 3.5 final drive in. I now have a 3.9 final drive. Bobby has told me that every car he has tuned with shorter gears always drops power on the dyno.

I say switch to Motordyne ART and if you upgrade cams i'm very interested in seeing what set up you decide to go with as i've been debating for a few months now if i wanna go that route, as far as a 75-100 shot, DO IT! I'm calling no ***** now
