look, I can't limit my cent. at 3500 rpm my spring combo brings in 14 degrees so with 22 initial. That's 36 degrees at 3500 rpm. Here's the kicker, at my redline... 5500 my weights will pull in 20 degrees. So with a base of 22, at 5500 rpm it will have a total timing of 42 degrees advance. That's because I am using a stock hei. I've only changed the coil and mod. I've changed the weights and springs
