OBDII programing and tuning

[k120189]

I figured seeing as there is a lot i don't know....and that im sure a few others are in the same boat...what does it take to tune an obdII vehicle? OBDI used epromms and there are many after market solutions to that such as promintator and dynamic efi which replace the epromm with a flash chip. or u can just burn chips. so what about us OBDII folks with newer astrofari's. theres power programmers which are out of alot of peoples price ranges... is there a pc program/ cable option? and what kinda of prices are those?

There are some really nice and $$$ software out there to hook up with the laptop. Or the cheaper Hypertech / JetChip stuff which basically only gives some slight mods at WOT. The JetChip is a bit better when not under full load. Someone else will chime in with more details.
