sorry I'm not really talking about the power loss the poster is talking about anymore. I'm talking about if vtec is engaging properly or not. And a cat is not going to make a difference for those vtec cams to engage.

If we are going to find out what exactly is wrong with that guys car, he needs to post more information about what the car is doing. Reading the description it could be alot of things other than cams or a clogged cat.
