I've made the following mods to my RX8:

-New Racing Beat Header
-New Agency Power cat-back exhaust system
-New SRMotorsports cold-air intake
-New SRMotorsports underdrive pulleys

and I also just recently purchased a hypertech ecu programmer. Unfortunately I'm currently having issues with my programmer. It gave me an error code (7E: Internal Error) and I'm currently discussing that issue with hypertech. After making these mods, my car is running very sluggish. I have to rev my RPMs to at least 2000 just to get my car moving. I'm not sure what is going on, but does anyone have any ideas?

 

Miles? Year? Last spark plug change? Stock Coils? Compression test?

lots of information you need to divulge before anyone can remotely answer

 

It is a 2004 with 72,000 miles. The spark plugs were changed about 3-4 months ago and the coils are stock. I have not performed a compression test yet.
