That banks box looks sweet but dont know much about it. I have a K&N FiPK, Airaid Throttle body spacer, Ebay long tube race header and Y-pipe kit currently and getting ready to install dynomax cat back kit. I didnt gain much with the cold air by itself especially because of the stock exhaust but after I installed the long tube headers it really woke up. If i keep my foot out of it i get about 14mpg city with my 03 Z71 Tahoe, stock I was getting 10 mpg. I cant wait to get a custom tune!

i liked the cold air and hypertech on my tahoe. the hypertech mostly because i wanted my speedo to work right but it did help out alot with the hesitation on shifts. i only ran the 89 octane tune so not much there. probably woulda been better runnin premium. with the two of them together on 33s i went from 12-13 mpg to a pretty consistant 15. sometimes even 16. by the way. sent you a pm.
