The problem I run into is there are tons of power tuners, easy fix: add fuel and timing...higher shift points, everyone can do it.
BUT I cannot not find any tuners that will program what GM did back in the 80s and 90s, program the computer to lean out at a cruse setting of light load and light throttle, and to fade back to normal A/F ratios at any incress in load and throttle.
They seemly are afraid of the old wife's tail of burning up an engine by running lean.
I have tested all of that and under light load and throttle there is no danger, that IS a risk at full throttle and higher RPMS as in a race but if programed to switch back to normal A/F tables no risk.
