so-so fm13 results Air Fuel was 12.9-13.2 for the last run, first run was 12.5-13
No knock at all.
Timing was showing 30.5 5800rpm and up. Slight dip at peak torque. I'm thinking next time to drop it down more.
Numbers are STD, I asked for SAE but they were clueless and couldn't figure it out. I assume with SAE they would be a little better because of the weather 29.60in/hg, 93degrees and 33% humidity(according to the dynosheet, although it felt like 80-90% humidity).
Before #'s 340/358(with all the mods listed except tuning and the cam)
Mods: FM13(230"/232" .595"/.585" 112LSA), PRC dual springs and harden pushrods, Double-Roller timing chain, Jet Hot LT's & true duals(magnaflow 4x9) !cats, RAM Powergrip clutch, Whisper lid(fram filter), FTRA, Shaner 2 Throttle Body, NGK TR55's, Taylor wires, SLP SFC, BMR LCA's, BMR PHB, BMR Torque Arm, TA girdle w/stud kit, Hptuners/LM1 Wideband, Nitto 555R DR, SLP Line Lock, Pro 5.0, Shiftlight
(387/373)
I've done the tuning myself, I know there is a lot more it in so I'm going to keep working at the tune but this is a decent starting point. If anyone has any suggestions, comments or questions please post them.

sounds about right for the conidtions, although, admitadly on the lowside. A friend with an amost identicle set up did 398.3. He was pushing that through shitty 98 heads tho(853 casting, i think?). He had true duals, LSX78mm, ported TB, and the same cam. What kind of timing were you seeing?
