Well i ran 12.0 at 115 with my A-trim before upgrading with about 9#'s of boost at 5200, race weight at 3300# with me. Here is my set-up:
-base timing at 15-16 degrees, take extra out via BTM if you get it...it helps alot. With the timing up that high, you have an awesome bottom end and yet still retain great topend as boost comes in.
-TPS to 1.1-1.2 volts, key on car off
-I don't have a fuel gauge that i can watch under boost but i think it is still set at 43#'s at no vacuum
I ran the autolite 23's, one step colder
No chip and have FMU, i think 8:1 for 24# injectors?? Can't remember but it is the right one.
As long as i ran 93 and not crappy "supposed" to be 93 i never got detonation. I ran it this way at the track too. You might think the TPS should be below 1 volt but trust me, it seems the higher i put mine as well as my boss(March issue of 5.0, "Trading Places") does, the better our cars run.
Hope this helps.
Oh and yes the MSD BTM is worth it, other wise you have to leave your stock timing down so it won't advance too much topend and induce detontation.
