Much better stated, I did say marginal i.e. as some difference but not a super crazy amount. Though like I did state it really cleans things up engine wise and underhood wise. I also concur on the Standalone, The PowerFC was definitely one of the best things I could do on the stock engine. Props for posting with real info.
