Thanks guys.....I wasn't worried about it, just kinda curious since I have to make a 400 mile round trip twice a month....Either way it's still better than my truck, which gets 10mpg downhill

No, it doesn't have a carb. And there is nothing wrong with it. That's what you get with an automatic trans when you do gears, stall, etc. M6 guys will get much better gas milage. If your worried about gas milage just leave it alone. Go buy a nice Prius or something. :P

Where would you get this so called "lighter" right foot you speak of? It doesn't sound like much fun. I don't know how much more tuned up I can get. I run a wideband and part throttle is near stoich all the time. Opti is brand new ac delco. Good plugs and wires, MSD coil. I am a professional mechanic, I think it runs pretty good. If your getting WAY better than that with a GM 847 perhaps your leaving lots of power on the table to get better gas milage. If I baby it I can get 12-13 mpg but it's not much fun.
