Not cheap, but the only things other than FI that are really going to give you noticeable gains, are heads and gears. And the gears won't do anything to raise the dyno numbers, just make you quicker.

Do you have an automatic or a 6 speed?

For the auto I'd recommend a 3:42 gear ratio
For the 6 speed, I'd go with a 3:73 or 3:90

I got a 6 speed, so if I put the 373 it won't slow down like a second gear roll to redlining 4th gear?

No it wont slow you down. Plus with the cam kit I'm sure you are upgrading the valvetrain so you can rev it up a little more.
