I have a BRF gov in my CZF trans and pinned the gov. spring, I didn't drill any holes though as I wanted to get the WOT shifts down bettween 5000-5500, well now it's at 4500-4800. Only vb mods are Superior's line bias spring, tv valve & plunger spring, also stiffer 1-2 & 3-4 accum springs and 6 holes in the sep plate I believe they were 3rd clutch feed, 2nd clutch feed, rnd4d3 ori, rnd4 ori, 3rd accum, and tv balance not sure on the names but sure their the one to be drilled. Anyway the trans shifts awsome! Just want to raise the shift points about 500rpm, I was thinking maybe two 1/8" holes on the gov weight, will this be too much?
