Hello
Hello Everyone,
I just bought a 1999 XLT 4.6 Auto 4x2 with 50K on the clock. I've had it about a month now. I joined F150 and F150online and learned about the Evo and Gryphon. I just ordered a Gryphon today and am looking forward to getting it and some tunes to see what this is all about. I'm thinking of a 87 towing, 87 performance, and maybe another 87 towing optimized for higher altitude because I occasionally tow in NC at around 3000 ft. But the trailer is only about 1500# so maybe I don't need anything special. I doubt I'll run 91 or higher octane, I'm mostly interested in improving mileage and performance while towing my light trailer.
