i wasnt really sure whether to post this thread in the cobalt owners lounge or here so here i am. i decided to test out the I that us 4speeds have. i think it stands for incline? anyway, i found that in that gear the car will actually stay at a higher RPM when pressing the gas and when my foot is off the pedal. this in turn increased my accleration. the only negative i found was when slowing down to about the 20-40mph range i felt like my car stalled or lurched for a moment. idk if it really stalled or maybe downshifted? i have a shift plus in on stage 1 if that helps but if anyone else has tried this or knows anything about this i'd love to hear it.
