How much did you advance your diablo's timing?

The base predator tune is pretty close to optimal. Every car is different though, you will just have to get on a dyno and play with it... Min's a 2000 M6 and I make max power wth 30-31 degrees at WOT

Advance +2% at a time until you see KR during the
acceleration. Then back off that 2% and another
couple for luck. 3.5% is roughly 1 degree of timing.
Best timing is usually about 2 degrees less than ping.
So find light ping and step back out, and you're there.
Note that you may see transient KR from throttle
opening (tip-in), shift events, etc. that happens
below your ideal WOT spark. Nothing you can do about
this with the Predator on your own. Best to roll into the
throttle slow, so as to minimize this source of KR and
let you see the real situation (stock KR is too persistent
to see what's going on, for seconds after the blip).
