Anyone have any feedback on why my 1999 SE seems to top out around 120? I have all the performance mods talked about on the site. Including air-intake, a complete exhaust system, and a flashed computer. The only thing I lack is a supercharger. She screams but just seems to drag around 120.

Thanks in advance for the feedback!

 

Mine pulls easily to 130 and after that it starts to slowly creep.
