hey paul did you change your plugs to a colder plug or leave them, i am gonna run the 75 shot and heard it is a good idea to avoid detonation but is it worth it because i know our cars have 12 plugs and looks like a nightmare. also did you do anything about timing or just leave it and have you gotten dyno graphs while spraying. i am just worried about the trac. control hitting while spraying because it will instantly go lean for a moment if that happens i believe. also if you did change plugs let me know what the number on the plug is if you did go colder, also what is the stock plug number anyone??
