check your timing

Check your MAF.

you think so cause it idles just fine and revs just fine... just when i gas it on the freeway it doesn't pass 4k rpm it just sputters.

[Mr.s13r]

I mean the CAS might need to be turn up a lil. Same thing happen on my friend's kade and that's what we did advance the time a lil.

Check:

-Timing
-Spark Plugs
-Minor Boost Leak
