Whats the story on the tune on these. Everyone I have seen use one of the kits, always seems to need a tune. But a lot of the builds changed cams or something else. Would it run the "stock" motor just fine with no need for a tune? It would really change my direction one way of the other..

 

Can you post a link or something? i don't know what you are talking about.

 

Yeah no problem.

Interested to hear about the tunes in any of the available pre programmed gm controllers, not just this one. They are the same kits that come with the connect and cruise packages from gm as well. I think a few members have used them. I remember reading about the dbw pedal assembly sucking to install or something.

 

What engine do you have? The controller won't work on some of the more common engines used for LSx swaps.
