Depends how large of a pipe you have it in. Once you max out the MAF (5.0v) in the stock 2.75" MAF-housing you can step up to a 3 or 3.5". The downside of doing that is less resolution meaning idle and low-speed drivability can suffer. My car is pretty much at the limit for the stock housing, I max it out during long 5th gear pulls into the higher RPM's.
