What is the best/safest programer/chip for LBZ

[mark45678]

Any empty mpg changes? Should be across 20mpg on a flat road at 60-65 mph.

The way my truck was before the tune I was seeing 15~16 mpg with a heavy foot at speeds 75 ~80 mph , Now its 17+ MPG with the last 3 tank fulls empty. Towing shows a solid 1~1.5 MPG better then stock with 9200 pounds of 31' holiday rambler in tow. Power to spare in the hills and keep me smileing .

Thanks again John !
