timing at Peak TQ and Peak HP what was your timing at Peak TQ and Peak HP...also what AFR did you get best tq at? and best HP...going to dyno monday and trying to see what changes to make....its a HCI Z06...WOT fueling is pretty close right now...26 degrees in the upper RPMs...I'll attach the tune...check out my timing table and PE vs RPM(should I lean out at upper RPMs or leave it the way it is)...still working on the VE table
eh disregard attaching those....too big for the forum...PM me and I'll email em to ya if you care to take a look

Best AFR & Timing will really depend on the combination, if you are using one of hptuners real time tuning custom operating systems you could quickly add or subtract timing in real time or adjust your PE/MAF/VE tables all in real time to adjust your fueling so your not wasting time flashing in between runs.
Edit:Just noticed you are using efilive so you probably won't be able to tune in real time so I would say start at 22* & work up from there, once you find optimal timing back it off a degree or two once power starts dropping off, fueling depending on the type of dyno would probably like to be anywhere from 12:2-12:8:1 more than likely.

I have my PE 13.1 slopes down to 12.5 at peak tq area(4400) then 12.55 from 4800 to redline.....EFILive has the DVT controls feature....I can enable it say for 5 consecutive pulls....start out -2(takes 2 degrees out of the whole timing table) then go -1 then 0, 1, 2 to see where it makes more and less....then I guess Ill change my timing table accordingly....right now my upper RPM timing in the max HP region is 26 and in the peak TQ region is 24....i figure + or - 2 degrees from there should be pretty close
I guess after I figure out where it makes best HP and TQ with timing I'll try bumping the PE up to 12.7 at WOT and see what that does for numbers
