Single tune plug and play chip. Was in my 95 250 before I got my TS 6 position. Has decent power and got 15-16 mpg on 35s. Had no problems with it whatsoever
I have tried to sell one for the last 5 years. No one is interested in his programing. I even posted it somewhere in a "you pay the shipping" and got no response. Good luck with your sale.
Haha I'm starting to realize that. I mean I never had a problem with it. I ran it for 6-7 months before I got all the parts for my build. Is there something idk about his tuning?
