Thanks, Jerry. The guy I bought it from is from Cary, NC. He does tuning for DS and SCT tuners. I got it with the Stage 1 unlimited tuning. He'll modify the tune to match my mods for as long as I own the truck which will come in handy when the day comes that I decide to rebuild or replace the engine (hopefully no time soon).awesome! you wont be disappointed, the 93 tune is pretty nice!
