First off, I know every person here will tell me to go with efi live. If you read my sig you'll notice I do have EFI and don't have an LBZ. So don't so that.:thumb: My uncle is looking to pick up a little power without being too obnoxious. I am pointing him towards a 4" exhaust, downpipe back, with a muffler. I also dont want him to burn up his trans and I know if he has enough power to smoke the trans he will. Also he wants to be able to unplug the unit and go back to stock if he needs to and have switch on the fly. This has lead me to the Edge Evolution. It seems cost effective and with 100hp over stock it should give him the power he wants without hurting the motorand trans. Opinions? Go.
