Intake/Throttle Body Question

[89 chevy]

Is it worth it to buy a different Intake, or bigger throttle body for my 03' Yukon? I have Headers, Bassani Exhaust, and Cold Air intake. I am waiting for a scan cable from Black Bear for a Tune.

Thanks
Elliot

If you change the intake you will have to go to electric fans because the LS intake will put the throttle body in a lower position, which is right in the middle of the fan. From what I have read, the truck intake manifolds flow really well up until about 5k rpm. Then they choke above that. Im hoping to throw an LS6 intake on soon. Just got done building one car so I need to rebuild the funds to get the Tahoe the way I want it!
