So I just got my first Viper of my very own a little over a week ago (my mom has a 94). It's an 04 that's mostly stock aside from a K&N intake and a set of Borla mufflers (fairly sure all the cats are still there). The gentleman I bought it off of had an SCT tuner with two customs tunes that he gave me as well, one for hot weather and one for cold. Since it's mostly been under 50 here in Kansas I originally put in the cold tune, but the more I thought about it and because I didn't know where the tune came from I decided to go back to the stock tune and mess with a custom tune later where I'd know what I was getting. That being said, since the car came from a different region (bought it out of Mississippi), I got to wondering if resetting the PCM and all the adaptives would serve me any good so the car could "learn" the new environment quicker from a blank slate or if I'm better off leaving it as is. On another note, part of this comes from the fuel mileage I've seen with the car. Granted I know it's a Viper and believe me, I plan to have my fun with it, but in the 13 hours I drove it home I was only seeing around 16 mpg on the highway when I hear a lot of you are getting closer to 20. Since I'm pretty much daily driving it to work (around 5-10 miles in town and ~20 on the highway), it never hurts to be able to go a little longer between fill ups. One last observation I've had is that I don't know how people can complain about the skip shift. Unless there is something way messed up with my car I cannot seem to make it go off if I try. I've tried lugging it down as slow as I can in first and it won't even light up. Not to mention shifting out of first under 20 mph would pretty much mean by the time my foot is off the clutch I'd have to be pressing it right back down .
