covertrussian Posted October 18, 2019 Share Posted October 18, 2019 I made a thread about it back in 2016: AVCS Timing And Overlap (2005-06 vs 2007-09) I used the FSM to gather that information and then plot it on a degree wheel. But I believe 2005 FSM has a typo on the exhaust closing at 5* BDTC. While all other FSM's say 5* ADTC. 05 LGT 16G 14psi 290whp/30mpg (SOLD) 12 OBP Stock 130whp/27mpg@87 Oct 00 G20t GT28r 10psi 250whp/36mpg 22 Ascent STOCK Link to comment Share on other sites More sharing options...
