I'm also running stock airbox w/ k&n drop in. I dynoed around 550 on the 82 pulley. I definitely feel at this power level, it is a restriction. Once I upgrade injectors and idlers, I plan to get the JLT, L&M 66 Tb and run 82 so I hit my whp goal. My goal is mid 10s on my 20s with drag radials. I feel the bigger throttle body will net a solid gain from dyno graphs I've seen. Also going with 3.55s. Supposedly the dyno I was on reads about 15-20whp low, but again it's just a tool.
