Don't know about the quad....but i have the turbotweak chip. Took care of all my idle issues. Car runs perfect without any problems. Eric knows what he's doing with these chips and he responds to any problems you may have ( which there should,nt be any if you had givin him the correct setup that your running ). I like the idea that his chips are programed specifically to your cars combo and not one of those "one-chip-fits-all" types. This is just my opinion though !
