i got the 2.1 VCM Suite. im just learnin as i go cuz i havent got much help with this. i had 2-3 degrees of KR with my 3.4" mps. but i still had my NGK TR55 iridium plugs in at 0.060 gap. got the NGK TR6 V-power copper core plugs and gapped them at 0.050 and put my 3.2" mps on at the same time. went out for a run and saw 3-4 degrees KR. then i went into the low octane and high octane spark timing tables and highlighted the whole chart, then clicked add -3 degrees. went out for a run and saw only 1 degree of KR in first but 2-3 at the top of 2nd. i was satisfied with that and re-flashed my PCM with the 3 degrees pulled. so far that is the only thing i have changed. still learning......i have looked at the HP Tuner forum but didnt get much from searching.
