I have a 2004 Yukon XL Denali, and I am looking to get a few more horses out of it. What is the best bang for the buck perfromance upgrade? I am thinking a PCM tune might be the way to go. What do you guys think? Who would you recommend?

Your engine actually results in some pretty good gains, we typically see 25-30+ HP.

I contacted Black Bear and I plan on doing the USB cable to computer route for the diagnostic, and getting a tune from that data. My Denali is stock right now, so what do I need to do before I start the tune process? Change the O2 sensor?

Also what is everyone's thoughts on the K&N FIPK? Worth the money? They claim ~15hp gain, so that plus a tune could net about 35hp gain for around $600.
