Hey there. I got a digital timing light and decided to properly set my timing since I just had the distributer out for the intake manifold gasket. I have a couple questions for people who have experience advancing the timing.
First off I should say what mods I have that effect performance right? Jet stage1 chip, Hypertech coil and cap/rotor, Taylor 8.2mm Thundervolt wires, Autolite iridium xp plugs gapped to .035, flowmaster Y pipe w/ high flow cat. 3" single exhaust with race bullet, Ultimate tbi mods (stock fuel pressure regulator), TB spacer, intake. running on 85 octane (I'm at 6000ft above sea level)
Ok so here goes. I want max performance, but need some help understanding a couple things. My timing when I 1st checked (EST wire disconnected) with my Digital timing light was 13.8* advanced and she was running fine. I reset the timing to 12* advance.
1st question: When I plug the EST wire back in and check timing its way up there way past the marks on the balancer. Is this normal? its running smooth and seems like great performance.
2nd: Can I increase my spark plug gap from .035 to .045? what benefits can I gain from this?
3rd: How can I tell if I advance the timing to much or retard to much? What signs or symptoms am I looking/listening for? I know to listen for knock but I haven't heard any yet while tuning the distributor.
4: if I run 91 octane can I get more power out of her?
5. just school me on everything you know about tuning these engines, I feel like a noob.
