Will increasing the size of the ITR throttle body gain more power? Which is the best thing to do ; Modify the stock item or buying a larger one? If modifying the stock item is the choice I would appricate some help how this is done. Im a newbee and dont know much about tuning!

ITR is a `98 Eurospec which will be running a AEM CAI and cat back exhaust only!

 

RC can make the itr tb up to 64mm

Your money would be better spent elsewhere, especially on a nearly-stock C6.

 

They're an injector/fuel pump company - where does it say they do TB's??

 

http://www.ericksracing.com/throttlebody.htm

 

do a search no this...

erick's is out of most of their tb units now. don't go over 68mm unless you are really pushing some power.

 

I remember it kinda being hard to find on their website, but it does say something about TB's on their site. It costs $230 for them to overbore it. Give them a call if you can't find it on their site.
