i don't know to much about rotary accesories.....and i need to know what is a haltech,what it does,where can i get it and ...how much does it cost?

 

$1100usd or so.. it's a car computer that runs your fuel and spark. replaces your stock computer and all your stock wiring under the hood. requires rewiring the engine, and the computer is programed with a laptop. don't even think about doing it unless you know what you are doing....

it's required after you have lots of mods and high HP. like 300+

 

It's a little green elf that sits under your hood and blows tons of air into the inlet duct Damn, late on the post, scott beat me to it
