4.0 Performance Chip

Hey guys i got a question.

Ive seen Jet chips and venom 400 performance chips advertised on tv and in magazines. Does anyone have one of these installed in their 4.0? And if so does it work? Likes dislikes? MPG. Let me know, I need a little more uumph out of my 4.0. (I dont want to change the gears because i got the lovely automatic and i need to travel on the highway without running at 3500 rpm.)

I have to have a chip in my Z but I will share my experiences with you. If you insist on a chip/prom flash find a good programmer and have him do it custom. Prefabbed crap almost never gets your motor set right like a programmer can. One guy with a camaro LOST 5hp by putting a jet chip in.
