I have the opportunity to get a 69mm throttle body for an ecotec in a trade.
Does it make sense to switch to a 69mm throttle body on an ecotec w/ only aem cold air intake, header, high flow cat, 2.25" magnaflow exhaust?
Hell no. Thats way too big. I would only use that if i was running large ammounts of boost.
crackajax thanks, I did a search and came up with exactly what you said too big.

in my opinion, a 62mm is also too big for those mods listed. That might lose some low end power, but if you have cams or a p&p then the 62mm throttle body will help.
I got an e-mail today to buy a 69mm eco TB. Thaught it was way to big, so I searched the org. the guy KCCAutoInc is selling it for $250.
So even a 62 is too big for my mod's listed above? stay with factory? thanks
