At the big GTG Allen came up from SA to hang out and do some tunes/tweaking. Well I took my stock truck there for some laughs and a tune...man was I shocked after then tune!

I totally rid myself of that TqMgt. I run 93 octane too (by choice of me for max power), got shift points corrected, turned off Rear O2 sensors, turned off EGR, no speedlimiter, converter lockup delayed, and bumped my total timing a lot.

It was amazing how little timing this truck had at all levels. Up top it was pulling 40* of timing!!! :eek2: The thing was negative from what I remember up top.

No more dragging ass on the freeway now, accelerating from a dead stop is far easier, just general cruising is how this vehicle should have come from GM.

DO NOT hesistate to get even a stock truck tuned, the drivability is night and day.

And the kicker is...on the way back home to the Dallas area I averaged just under 20mpg...up from 17! :chug:
