Will i need a new tune for a new throttle body?

I currently have a C&L CAI, what size throttle body would be compatible with it?

Would a new throttle body offer any HP/TQ gains, if so what amount, if not what does it help improve?

 

the answer is. spend you money on something else. you will not gain anything from putting a TB on. if you are pushing some good boost numbers you will benefit from it but other than that not worth it. there has been lots of problems with aftermarket TB's and yes you would need a tune but dont get a TB. save your cash and get a driveshaft or something like that.

 

I had a friend actually loose power with one he tried it with the throttle body and without on the dyno and the owner of the dyno is our tuner. He sent his back to where he bought it from. I've heard nothing but bad stuff about TB. as you can see from my sig. I have every mod but that one.

 

I didnt need a tune and it was a great mod for a twin-screw!
