haha thats one problem...we dont know

my dad tried to bump the timing with a gun that u use on a chevy, ie it doesnt tell you the *...seince i bought the car i've use 93 oct, some times i would use oct booster and maybe 4 times seince i've had the car i've use 89oct in the intrests saving money but this was before we "bumped" the timing...as soon as i get a chance i'm gonna borrow my buddies timing gun and see exactly what its at...its should be at like 13* with 93 oct right?

Every engine is going to want different timing, be sure to set it with the spout out obviously and I would start with 13 degrees advanced and move up 2 degrees after each test run(spout in for run). Once you start pinging, back of the last two degrees and keep it there. Timing will be sensitive to the octane you are using at the time of tuning. If your going to run 89 in the car, then tune it with 89. The higher octane you run, the more timing you can run in the car. Let us know! Good luck.

I think my injectors need cleaning too, I would like to check into this schraeder valve connector, can you get everything you need from a parts store?
thnx
Btw, friend of mine had to send back a defective msd coil, it was new, but made the engine pop under load over 3k.
good luck.
