Not to sure what I am doing..

I have a 2003 F350 CC 4WD SRW 7.3l auto 4.11:1, with 305-70-16 tires Canadian truck and I am looking at doing a few basic mods. I have been searching the site and reading this forum about programmers/chips etc and am a little overwhelmed. I know I do NOT want a bunch of smoke like I am on Mad Max or something.

I gather from all the posts that the DP tuner is not the place to go, just kidding, they have so many referrals you would think that this is their site.

I am looking for a chip or programmer, exhaust and an air intake. I do mostly highway driving (work) and rarely pull a trailer. I was biased towards an Edge programmer till I found this site so now I am looking at the DP tuner chip or one from DPP. One question I have is can they compensate for tire and rear axle change and do you have to get a new program every time you make a change to gear ratio or tire size?

I was thinking 4" exhaust would be plenty but I don't want something really loud.

What would be the standard guages required?

A 4" exhaust is perfect for what you want to do. If you don't want too much noise be sure to install the muffler, it won't be much louder than stock. Get an open air intake of some sort, it's up to you it you want a name brand like AFE, S&B, or ARE or you can do the home made intake. As for gauges you'll need at least 3, go with a triple gauge A-pillar gauge mount with boost, pyro, and transmission temp gauges. Your right DP Tuner is about the best when it comes to ford trucks. Give them a call and they'll tell you everything you need to know.

DP is definitely the way to go. As far as tire size and axle ratio I think the chip does compensate for it. When you fill out the vehicle info form it asks you for tire size and gear ratio. I would think that you would have to get it retuned if you changed them but not sure.

There is nothing you have to do for gear ratio. No matter what gearing you are running, you're still running the same VSS gear ring inside the rear differential that reads your wheel speed. Tire size is the only thing that changes your speedo.

Kinda hate to steer you away from DP, but take a look at Tony Wildman while you're shopping. I've heard many good things about the tunes that Jody writes, and the tunes that Tony writes, so give 'em both a call and see who can do what you want the best. Good luck and let us know how it turns out....
