Timing to low Well got the H/C plus all the other mods done and the car dynoed 370 <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" /> I had some other driveline issues to resolve so I got them done and dynoed at only 330, the car seems slow on timing to me, gas milage went to hell. Power out of the hole seems slow to me but it pulls pretty good up top. Atap and scanners show it is making 31 advance at WOT and 20 at idle and 40 at PT, KR is disabled and scanners show 0 KR. The shop put a manual mark on and with a light it shows 19 at PT and 8 at idle. or roughly have of what the PCM thinks. Anyone have any ideas? Shop thinks the PCM could be bad and causing it, but I am just not sure how that could be.

Re: Timing to low Fuel is running 13:5:1 at WOT, I do not have the graph here, but torque was very low also and there was very little curve, it was almost flat 312rwtq the heads are custom stageII with 2.08x1.60 cam is 218/222 113LSA, the same setup as mine on another LS1 is making 417rwhp and 398rwtq. FLP with orp, LS6 intake ported TB, lid etc etc etc, all the bolt ons basicly. Just confused where the HP went. I had a o2 sensor problem but replaced it and problem went away, fuel is a little fat but not bad and would not explain a drop of 40hp and the shortage of 70hp.
