Torque convertor and detonation

Slow the advance curve if it only detonates at around 2200.. so make it maybe 2-4 degrees less timing at that rpm ..slowing the advance I guess it what it sounds like.... right?
You can have more stall and that will dictate more timing sooner, Sure... but that's not your problem so to speak.

To the comment above my post..
Just a reminder...The later the convertor stalls the later the LOAD is in the rpms..so if its not loading as hard..its not running through any detonation quicker or at all.
