Re: more efficient engine?
i allways thought, a chiped truck would get better mileage than a non chipped.
provided you controlled yourself.
is this not so ?
I think this is more true with an automatic trans than manual.
Line pressure can be bumped up to reduce slip.
Shift points, shift duration and other parameters can be changed for the better
Timing and other engine parameter adjustments will net better economy too.
So I think those with automatic trans can see better increases with a chip verses those with an automatic.
But even Dave got .75 MPG
improvement with a chip, and his manual trans and of course his driving habits tuned to max MPG
