intake and tune without a dobt. Looks like you are well on your way with ext mods

 

Throttle body, and exhaust(if you don't have it already). Simple bolt-on stuff.

 

why throttle body?

 

Bigger gear ratio 4.10 if you don't mind running high rpms on highway

 

If he's using the stock throttle body, a bigger aftermarket one should provide hp/torque gains and better throttle response. Plus it's a pretty easy install.

 

The stock throttle body flows enough cfms to support up to 500hp and wont hinder you up until that point

 

And not to mention the computer is not expecting to see that much o2 coming in and thus wil cause the car to run incorrectly.

 

Get a plan first. What is your goal? Naturally aspirated or forced induction.


Don't waste money on mods you will not need to realize your ultimate goal.

Need more info for sure, until then a tuner with free tunes.

 

The 62mm TB i put on my 06 worked well with the k&n cai I previously installed and noticeably improved throttle response. As for messing with the sensor, a tuner should take care of that. Just my experience though.
