Rev Xtreme tb's are the way to go if you want quality, and good person to go to if there is an issue. Tracy and Rev Xtreme got you covered.

Looking closely at the graph, especially in the 3500 and 4500 rpm areas and even up to around 5000 or so there are huge differences. +20 rwhp and +20 rwtq !! I suppose it may be a little more, or a little less in the areas in between but +20 rw hp/tq is a significant jump to me when its right in the heart of daily driving. Nice to know I got all the power under the curve that I can use, and don't have to rev the **** out of it to feel the power. Ok I am done babbling. I'll post more if anything else is done to the car.

Absolutely. I would suggest anyone going with 383 and up to open up the inlet on your fast 92 to 95 mm's and match a Rev Xtreme 95mm tb to it. If you got 440 ci's and up I'd say you should look into the Ported 92mm fast with a 100 mm inlet, paper gasket, and 100 mm tb. You can get the intake from Ron at Vengeance, and the TB from Tracy at RevXtreme 
To the bigger motor guys, that is unless you've already went sheetmetal, but a 100 mm inlet ported 92mm fast could be just what you need if you don't have the cash for the SHEET METAL.

To tell you the truth Mark, I am completely stunned at the amount of power the Rev Xtreme 95mm tb made vs the ls2 stock 90. Did you notice on the graph where there are areas that show gains of 20 rwhp and 20 rwtq !!! All in the rpms of what would be consider normal driving. She didn't just pick up PEAK hp/tq, she picked up power everywhere. I was hoping for a 5/5 return and figured it would show up above 6000 rpms, but to see the power start going up from 3000 rpms just made me smile even more. Gotta say it again, thanks Tracy Lewis. You got a great tb being sold over there at Rev Xtreme.

I saw that. I was pretty impressed by those gains.

Yup me too, but the paper gasket vs keeping the O ring intact helped me decide to go with the 95 inlet 95 mm tb combo. The 346 guy you are talking about has a bad *** forged 348. I am just waiting for him to post some times N/A and with some Nitrous. He's got a mean 348 on his hands.

I don't really know. Another member on here went with a 103mm maf and only picked up 3 rwhp if memory serves. Not sure it would be a good idea, although my setup is different from his, it is similar, and even if I picked up 5 rwhp it wouldn't justify the cost. Any donors ?? LOL
