Whats up guys? Recently snagged a 2014 PRO4X with 17,000 miles. Bilstein 5100's are already on, Bully Dog GT is on. 87 tune, 2* advance, WOT off. TOYO 33x12.50 MT on the way. I've had a Titan in the past with an Airaid MXP and I loved it. Here is the weird thing...

I'm a FFV and according to my BDGT, my AFR while cruising is 14.6-14.8 - which from what I've read is spot on. WOT it bounces 13.1-13.6. Is that not a little lean already? Could it have something to do with the BD? I was wanting to get a CAI, highly considered an S&B being a FFV, but it seems like it doesn't need to be leaner? Any ideas?

Dont rely on the BDGT for afr readings. Mine was a full point off from what the dyno read. Several guys have found this out as well. My mpg was off as well according to the pencil by 1mpg.. I run a S&B daily and have a MXP for race night, both are great on my FFV Titan.

Awesome. Thanks dude. My last MXP sounded great. Pretty loud over 3,500 RPM - but delicious. How does the S&B compare in interior resonance?

My AFR is right at 14.0-14.1 according to the Torque app. I wonder if it's reliable, though. At WOT, mine dips to 11.5-12-ish, so you're a tad lean, but in reality you're not too far off the mark and I wouldn't worry over it. If you're really concerned, get a dyno pull and see where it really is.
