OK, So I am finally getting my car back this wed/thurs. with its repaired body, u/l control arms, four new tires ( yokohama AVS es 100's) drop springs, subframe connectors, ect... anyway, I have the 93 octane tune in it now and thats gonna be changed as soon as I get it back, anyone know how far I will have to back off the timing to run 87 again, will I have to go all the way back to stock or can I keep it a little advanced? It would be just way to damn expensive to run 93 just for regular driving back and fourth to work, I plan on having 2 tunes, one for commuting and then one for the track. Any input appreciated..

Also, I have and am waiting to install, 75mm t/b, port/polish my plenum, transgo stage 2 shift kit, t/b and plenum spacers.

i use 87 octane with 2 degrees advanced over stock. no detonation but i also have an engine oil cooler installed which i believe helps keep the temp down in the combustion chamber
