How do you like the Blackhawk intake? Any throttle or MPG gains? I always lose MPG because I can't keep my foot off the gas with these mods...

To be honest, I only felt a slight change but not much. Only real significant change is the louder exhaust and sucking from the intake.

Update:

 

Well, I got the 7-9 McGaughys SS kit, 1.5" add a leaf, and 37x13.50R22 Toyo Open Country MTs on their way in the mail, but still can't decide on whether I want to go with the 22x10-13 with the smaller lip and a better chance of fitting without cutting the front bumper and wheel well flares or the 22x12-44 with the bigger lip and guaranteed to have to cut the front bumper a bit and possibly the wheel well flares unless I get a 1.5-3" body lift. Keep in mind some shops say the bumper may have to get cut to fit the 22x10-13 in that case I would just go with the 12 wides. Feels like a very difficult decision. What should I do? haha

Set it to 9" and try it, is what I say.
