My 2005 CTS-V

Did a couple quick WOT pulls on Friday afternoon, something feels weird above 4k rpms, so I let off without going to redline. Feels great under 4k, then it feels like it breaks up or something, and gets slower. So I'm going to take it back to Shane to do some street logging to check out what's happening.

Not sure if losing 45lbs off the flywheel changed the load on the engine enough to need some retuning.
