The Maximum Overdrive was Kiger's chip that had the insane-o timing in it. I do believe it was 36 degrees.
I THINK I have a GNX HiFlow on my hard drive still.. let me look and see what the timing is/was.
Nope.. got the Max OD and it was 36 degrees. I THINK the GNX HiFlow was 32 degrees. High timing for sure but on a relatively mild setup, probably still okay to use.
Once you go to bigger turbos tho, the high timing stuff really starts working against you.
