Thanks for the replies.

Blacdout96, what sort of performance improvements can I expect from a V6 "off the shelf" tune?

I really don't expect great HP increase (if any), but I would hope for more spirited shifting and better MPG. I read where a good tune usually gives an increase in MPG on highway, and hopefully, that would offset the loss caused by changing to 3.73 gears.

One thing that always amazed me is why people spend big bucks hot rodding their motors, but don't spend a few bucks on trans and engine oil coolers. These two simple to install coolers will make the hot rod motor and trans last so much longer than if they are not added. My personal experience is for the $60 trans cooler and $80 engine oil cooler w/remote filter, the pay back is insurance against scored cams, cylinders, and spun main bearings under hard use. If added to a stock drive train, expect 200K of usable life before trans failure, oil consumption, etc.

JMHO.

Regards,

Mark
