I still have the 94/95 "ported" TB Floz sold me in the garage. Maybe I'll give it another try. Did it affect MPG, and about how much power do you think you gained?

I am assuming you have some sort of scan tool to view your O2'* right? It is better to use that to adjust your Air-Fuel Ratio than it is to use an actual air-fuel guage because those aren't accurate at all at WOT, which is when it is important. You may have your AFC set WAY to rich. You will make the most power running as lean as you can without KR, but their is a point when you are running too lean which i think is O2'* of .87. My dad has his Mini-AFC set at 88%, and he is still running rich.

I was just making sure, don't need fellow car enthusiast blowing things up. Yeah, I know about the LS1 throttle body conversions, my dad ordered one for his GTP but canceled the order at the last minute because of other minor mods that he figured out would be cheaper and make more difference after he went to the track. (Smaller Pulley, Fuel Pressure Guage so he can adjust fuel pressure, etc.) Those LS1 TB'* are nice, but anyways, shouldn't air fuel ratio at idle be 14.7? On the 97+ '* 870mv is as lean as you want to go, and between 870 & 930 is a good range. Obviously this is much different on the pre 97'*.
