For those of us with the direct injection V6, how much does the tuning school gm gen V book cross over?
There seems to be so many v6 Camaro, Cadillac and Colorado/canyons. Seems most are going with trifecta because they are the only ones that don?t give a puzzled look when asked.
So for those of us trying to learn and trying to massage our lgz, lgx and lfx motors, and the 8l45 transmissions, are there any guides etc?
