I am contemplating buying the LS1 edit but would first like to know what I can expect performance wise. Do you have complete control over the engine and trans? Anyone have complaints?

 

you can do almost anything you want with it. only complaint is that the manual sucks, and if you don't know what to modify for any particular item you can make things worse. if you can figure it out, i don't see why up to .5 couldn't be gained with proper tuning. ed wright makes bigger claims than that.
