I zeroed out mine on my 5.3 and it seems like it will be a lot eaiser to tune spark now.
F-Bodies and Corvettes don't use them and they go into PE instantly and so do I.
What does everyone else think about it?
And ive always thought a richer fuel mixture (12.5-13) burned slower, which required more timing thats why there was a fuel mixture spark correction table)
But after reading more a richer mixture burns faster while a leaner burns slower?
