Hey guys i am knew to the thread and i was wondering if u guys could answer some questions. I am a college student that commutes about 70 miles a day, 3 days a week, to school. and am looking at something to increase gas mileage. Now i have been looking into this tuner for a while and am pretty sure i am going 2 get it but i just need some reassurance. Cause i have been told some other places to just get it dyno tuned, but realized dyno tuned doesn't let u switch parameters so your just going to get either better fuel or hp. Right so gryphon is def the way to go?

I know there is 3 programs and i was thinking about the getting the tranny one, the 87 tow, and the 87 performance. But my question is what is the difference like one is more hp and torque while the other is better mpg? And specifically what is the difference between the 87 tow and 87 tow custom? And am i really going to notice more hp and mpg?

Another thing is i have 187000 miles on my 03 f150, so my question is if my engine dies would i be able to use this after replacing the engine?

One more thing is i was looking into getting an exhaust and really like the price of the gibson on autoanything.com ($397 shipped). Would this also improve my gas mileage and hp and should i get this before or after i order my gryphon?

thanks
