all of them had custom tunes. even if you can get by without a retune any engine will perform tons better with a fully custom tune datalogged and all that. im assuming you can but then again thats only an assumption. so no i dont know for certain.
and yea cleaning out the whole throttle body is a great idea, rebuild kits were cheap last time i bought a couple and it was worth the few bucks to do it.
