When i bought my car the owner said he had a predator tuner and i never got it. He wouldn’t return my calls, so now i have no tuner. Well i plan on buying a Xcalibor2 and was wondering if i can install that without the predator tuner. It may be a dumb question but i don’t know much of anything about these things, and i don’t want to run into anything dumb. I was also wondering if anyone knew any sct tuners in the Maryland area. Thanks guys
