I see there's a couple on craigslist for sale reasonablly - an Edge and a Superchip brand. Is one better than the other. Anybody have experience with them? I usually preach not putting anything on one, but if I can use economy mode and get more MPG I may be all for it...
Bullet proof engine and yours has the earlier rods which are more desirable and much more stronger.

Ive had several including 7.3 P-stroke duallie crew cab that did 18 mpg on occasion.
