okay so i made my igl w/ everything having 15 split for igt. and i did all my settings. I have NOT done any fuel stuff yet. the timing i'm running is alot less then what was originally on my maps, It was close to stock now i have a very conservative single tune on it. 12-13 range in peak boost/high rpms and everything else smoothed around that. i'm wondering if i could upload these new timing maps and still have the car run basically the same. i'm still waiting to install my wideband b4 i go at the fuel maps. this is probably a pretty newb question but my brian is fried from staring at number logs all nite ....
