1996 ImpalaSS WX3
I’m currently running 3.08’s in the diff.Hey SoCal,
How did you end up liking these settings? I compared them to what I've come up with and there are similarities and differences. But I also have a 2.56 geared wagon so that could explain some of the difference. I've also made trans shift changes such as keeping the converter locked up and tweaking shift points.
I'm set pretty aggressively and do get some slight surging now and then. It is almost not noticeable. I may need to make further changes once I get the exhaust done. Once I'm able to hear the engine the slight surge may be much more noticeable.
I only set the retard to 17.5 initially to get a feel for it, i also didn’t want to be too aggressive with the rear end after reading about aggravating a “Clunk”in an earlier post.
It feels pretty good, I can “feel” the decel occurring gently since it’s real light yet and not a head jerk.
I’m not getting any surges at all and no problems at lower rpms...
I’ve still got to address the shift points and TCC lockup settings, then take it up to 20 degrees of retard, but so far so good
