throttle body or Long tubes
Which would be the best modification to go with. A 90mm throttle body or some long tubes. As of now I have bullet exhaust, o/r x pipe, intake,and tuner. If i go with the long tubes do i have to have a custom tune? Just want everyones opinion on which would be best to do first.

Im sure it would help but I figured as long as you were keeping the cats it wouldnt matter much. I ran mine for about an hour without a tune for my Long tubes and my car ran fine.

TB is worthless unless you're pushing massive amounts of boost. Go for the LT's, but make sure you get your mid-pipe from the same company. If you mix-n-match you might have fitment issues. You will most definitely need a tune. The car will start and run fine, but it will be running lean due to the repositioning of the O2 sensors.
