2006 gt problems

[tonyjrd]

I have an 06 gt. I recently got a steeda package that came with cold air intake, flash programmer, x-pipe w/ high flow cats, and underdrive pulleys. After I got that put on I put on a throttle body spacer and slp loudmouths. Now my car is messing up. Its real sluggish. When I try to get on it, the engine revs and everything but it doesn't go anywhere. I can drive it real easy and barely even notice anything wrong. I took it to the dealership and they thought it was the fuel pump so they replaced it but its still doing the same thing. Anyone have any ideas of what is going on? Could it be my aftermarket parts?

not trying to be mean but you sure its not the clutch slipping/glazed over? or if its an auto low fluid?

that definitely sounds like the symptoms of a bad clutch more than anything else.

My buddy and I thought it was the clutch and thats what I told the dealership but they told me it wasn't.
