OK, now , with the help of some Moparts buddies, we swapped to the 7AL and matching coil. All we had was a 7000 rpm chip. Added more 93 octane, and this was Sat morn.

100 foot from the traps, I hit the rpm chip. Also, checked the plugs, dead white. We swapped in four - 93 jets into the APD- prepped Dominator replacing the 90's.

OK, added another 1/2 gal 93, so all the 110 was surely gone. Forgot to charge the battery, got to the lanes, car died, towed to get it jumped. By the time I re-ran, car was 180 already. I was flustered. Wasted run

I had 2 inches of 93 in the tank. I added 2 inches of 114. Last run, Kahn from Bob George Racing gave me a 7400 chip. THANK YOU !!

It liked a little bit of race fuel. Timing is locked @ 35 deg. Plugs looked better after this pass.

To sum it up, My best runs were with the 6 box. I am keeping the 7 hooked up until Indy. Thenn I'll make some passes, then switch back to the 6. I think I was on a run with the 7 until I hit the chip. Then I think running the 93 octane played a part. More or less, I think using the 7, and jetting up would have netted me better passes.
