??? I just finished a gen 1 1507 build. -2.5mm Carrillo rods, no spacer, gen 2 crank w/ cb gear removed and lightened by APE, CP slugs @ 13.7 CR, APE full head package, 415/395 web cams, PC5-PC5 Ignition-PC5 Autotune, 69lb bosch injectors, MPS 62lb reflash, and much more.
I couldn't get a decent idle out of it w/o +14 of advance on the PC5. The pipes were glowing at 5-6k on the dyno until I went north of +10 advance on the PC5. What would cause the fuel to burn in the pipes other than retarded timing? The farther I go with the timing the better it runs. Kind of scaring me. What would throw the ignition timing off by 15+ degrees w/o keeping the engine from running at all? Stupid amounts of exhaust pressure coming from the pipe, this seems impressive. Will idle smooth at 1400rpm on a very rough and unfinished fuel tune.
