OK, I am hopefully going to stick the motor back in tomorrow, or maybe wed. I got the pump gear on and timed today and the cover on, but am having second thoughts on the timing. I have it set at stock right now(11-12*) and since I still have the motor out, I think I want to reset it again while its easy to get to. My question is, what should I run? My mods are Fass 200, 180 pump with 5kgsk and 0 plate, AFC tweeked, (but not sure how much since I didn't do the work), 7x12 24V injectors, Hamilton springs, Maxspool 2.5++ cam, ATI dampner and s465. Its mostly a puller that I may drive on the weekends here and there. I'm thinking a happy medium would be 20-22*? Whats everyone's thoughts?
 
Im at 20 on the pump with ddps 175s, and 024s and im just outside the bowl. It really depends on injector pop off and spray pattern. I know when I put the 024s in it bumped the timming up and also the ddps did due to pop off pressure. I would start at 18 and go from there. 15 was no where enough with 181s. Ill put a light on my truck and see what its at but it sounds like more than my brothers 12v at 25.
