Stock WK2s around this time would do 12.9 at the track, fast forward to spring and summer weather and they were running low 13's. DA plays a huge role in power made by a NA engine.
Yeah, that makes sense. It just started cooling off here down south, so I have been feeling way less than full output since I purchased in June. We had a record number for days above 100 deg and endured weeks from 104-108 deg. Add the humidity and its almost like your at 5000 ft. elevation. People have posted 10 wheel HP for the CAI's and like another 10 WHP and 15lbs torque for the Borla. It still seems like that would us close to 500 at the crank with those two alone. Alas, I guess its just wishful thinking on my part
Who knows though, a full Cat-back and a CMR might just us nipping at the heels of an X5M.
