my last 2 trucks - 2005 5.3 2wd 18mpg city 20 highway, the truck i have now 2007 5.3 afm 2wd oil burner 17mpg city 17 highway. they both had the same power.

we have a fleet of these trucks , over 125 of them. day by day these are coming into the shop with low oil levels or lifters that have failed. they dont think its if you will have problems with these afm engines but when. the upper brass are now looking at other manufactures.

i have a nbs that i've towed with since day 1 - its got 59,000 on it and its still shifting good. i would like to get my truck tuned but i dont want to gm to use that as a out if the tranny fails.
