yeah scratch that first part, i didn't see the "plus" part... oh well.
i didn't see the numbers, but i asked the shop to check them before and after the work, and they say it's good now.
i think the idle is a little more steady. not really a power difference, maybe a little smoother. my understanding is the cam deviation really only effects idle, not cruise operation.
my original problem was that after installing a full aftermarket exhaust, the car idled like crap, popping and backfiring and fuel trim numbers way lean. we tried all sorts of things, nothing fixed it. it ran fine with the MAF unplugged, which should indicate a bad MAF, but it did the same thing even with a new MAF. the only thing the shop could think of was that the deviation was out far enough to maybe cause the freer-flowing exhaust problems. maybe too free flowing? who knows.
i'm going to drive it for a while with the stock exhaust, then put on the new exhaust maybe after new years. i don't like having $2k worth of polished pipes sitting in a box in my garage.
