use the stock map, and then use a wideband to get it better, then use a dyno to tune your timing

retard the stock timing maps with 3 degrees.

add 10% fuel to the fuel maps, which doesn't matter so much since you're running in closed loop, so the ECU would correct itself ..

if you go boost, then that's a different story

just run OEM. no need to retard. that .8 difference in CR is not even 10hp

probably a good idea to run premium, too
yea... i had a stock muffler on a 2 1/4 pipe.. i unbolted the muffler just to see what would happen... its like a totally different car.. its soo much faster even my friend with the turbo del sol said he couldnt pull as hard lol:alky:

91 octane is a waste...y? that actually hurts ur performance...I ran 93 on my 11.7:1 at 19 degrees advance, no problems and can write u a decent base map...and the O2 only corrects so much...and even that u can adjust to limit its correction
