I've got a NIB Superchips Max Microtuner for a 2001-2002 Gm 4.3L V6.
It'll change some settings in the ECM to make the engine turn out more power and torque. It will also read codes, you can re-calibrate your speedo for different gears/tires, and you can remove the speed governor.
hey dude, this should work just fine on an '03 4.3 v6 too right? if it does man... i need this! there's almost no difference between the 02 and 03 chevy s10's with the 4.3....

well, yeap, went and called superchips, and they said the software used was totally different. said it wouldn't work on an 03, and superchips did not even make a programmer for a 2003 4.3 v6.
