Do I only need to set up the boost retard curve or should I set up the timing to RPM as well and what should I set it at .

Sorry for all the Q. I have never set one of these up and don't want to hurt anything.

I just used the boost regard with the distributor locked out.

This is what mine looked like. The distributer was locked at 42*. At cruise there was no retard giving it the affect of vacuum advance. I left a lot of timing in it until a couple pounds of boost and then pulled aggressively at first then more slowly. This was a pump gas tune.

Thanks , how much do you take out and when do you start.

I looked over my records and that was at 9psi and went high 6's in 100 degree heat on 93 oct.
Later I switched to E50, 1.48 60', [email protected], [email protected] on 15psi in good air. The motor is nothing special, 358w, AFR185, [email protected] .512" $99 HFT cam/lifter from summit, 9.2:1 cr, TorkerII intake, home modded 650dp, E50 fuel, 3400 lbs. This is the graph at 15psi.

Do you have any track times??

Brian...what plug gap did you run on the E50?

Brian...what plug gap did you run on the E50?

.020", a very famous tuner said you lose a lot of power if even one cylinder does not fire because of wide gaps and gain very little, if any from wide gaps. I tried .024" and worked with a non resistor plug and it worked, but the same plug in a resistor plug misfired under boost. I went back to .020" and never had another problem. I will say though that I never verified phasing on the rotor. That could have contributed to the problem.
