When I first start up everything is cool, I drive it around waiting for it to be at normal operating temps, then when I get on it in 1st everythings cool- boost builds normally, tires break loose and it nails the red line. But, when I shift into second it bogs until I let off, sounds like its missing or somehting. After it does this one time though it doesn't do it any more. I can floor it right after it does that waiting only as long as it takes to let off the gas and floor it again, and everything is fine. WTF is the deal? It only does it when I floor it for the fist time after sitting for a while.
