looking for some extra mpg

hey im sure this question ahs been asked a lot and it might b kinda like beating a dead horse but whats soom good tips for driving with the best fuel econ. i know it has a lot to do with location, hills, trffic, etc. most of my driving is half hwy and half city (base traffic for those military guys). im looking for more of a good rpm estimate or other mods i might b able to put on the truck. i normally keep my rpm @ or below 2k for acceleration and my avg cruise is @ 45-55 with an frp averaging at 6k.

Fasten your seat belts. Set back for the tuner review.

The main thing I found that works is try your best to keep the boost below 10psi when starting off, and travling down the highway.

If you can get/keep the converter locked with a higher tune, the mileage will go up some. The converter on the 250 tune isn't going to stay locked below 50 mph. The 275 and 310 tunes will yield better mileage in your mph range because they lock at 45 mph.

Have you contacted us??? If you purchased the tune once, you are not going to have to purchase it again. Did you purchase it directly from us, or through a vendor of ours?

Call the office Monday. Mick rarely gets on the forums, he just doesn't have the time these days. Talk with Donna, and let her know your issue....and that you paid for the tune through Rudy. If Donna is busy, then talk with Angela. She will get you taken care of also.
