Road Rage

ACLR8: I feel your pain, brother. This is probably one of the worst case scenarios of aftermarket modding, but in fairness to the other parties (who I don't know, or who said what), sometimes things are not known on "custom" parts for a while, and early adopters, as we say in the electronics game, are really Beta-testers. I know that does not make your situation any better, but you have some control over when you buy. On major mechanicals, I tend to be ultra-conservative. And even the mfr's often get it wrong - even Lexus has TSB's, recalls, etc.

However, I am no apologist or in anyone's pocket - I could not get a straight answer from Richmond or the Polydyn guys, and I consider that treatment quite specious. And I have not heard a very convincung case made for why 4.57's must make harmonic noise, and, say, a 4.56 dos not? I think it is likely that the 4.57 v.2 will, shall we say, "get it righter"?
