So after experimenting between ported and full manifold vacuum, all i can say is WOW! Ive drove the car now for several weeks with ported and fiddling with the va advance and it did ok but didnt really seem to have any get up and go. Idling was good for the most part, but in gear it would start to stumble sometimes.... Other times not. Today i went full manifold and set the VA locked out fully to the right with the adjusting screw. From this point the idling went perfect... Never stumbled again and held smooth no matter how long i sat there in gear. The takeoff and get up and go was damn scary with anything past 1/3 throttle....for me at least lol. Im not used to that little car behaving this way. I adjusted the VA advance to half way (8 turns....with 16 turns available) and it rattled bad under load. I then went 4 turns back right and it calmed down a lot. Finally settled on 3 full turns from 0 right. This gave me the least rattle and the get up and go was still maxed from what i could tell when i got on it hard. Im having a hard time hearing ping because im not sure really what it sounds like.... And the headers are so loud. Is ping the same thing as valve rattle? Total timing is set at 35 at 3000rpms. Initial falls at 12 advance. With VA hooked up it idles at close to 30. Adjusting idle doesnt change this 30 nor does adjusting VA canister....at idle. I assume this is ok. I adjusted idle to 850 in park.... It falls at 650 in drive. I just want to be sure im not killing it, but i have reduced the valve rattle sound almost completely and it runs very well.
