wht do i need for a dyno tune? i called a place near me about you and they said i need to get a programmer or some kind of control module to tune? lol wht do i need?!?!?!?!?

 

If they dont offer the tune for the cobalt, they just offer the dyno, you need someone with HPTuners to tune you.

 

Well you already heard it... HP Tuners is the program of choice for tuners of the LSJ!

 

You'll need

1. A dyno, seems like you found one
2. AFR readings. Check to see if the dyno shop will give you AFR readings if not you'll need a wideband.
3. Something to reprogram your cars computer. HPTuners is the prefered choice but I've heard of others.
4. Somebody with expierence to do the changes.

 

Even better said..

Just curious what are your mods OP?
