Had a customer send in some dyno files on a stock 2015 A8, 91 crap-tane, stock filter vs. BMS drop in.

30hp, 25 lb/ft from a filter? What the hell is GM putting in there from the factory??!!

Only 15hp of that is from the higher flow of the filter. The rest is from the leaner air/fuel ratio since the filter does some minor MAF rescaling. Basically, it's the same effect you get with all the Z06 intakes. Only it's $90 and looks stock. :)

Due to a lot of requests we ordered in a new GM high performance airbox and are working on optimizing a new drop in filter for it, like our current Z06 drop in filter. At quick glance we'll be able to make the opening larger, filter longer, with more pleats, and less cage structure for higher flow! w00t!

Model of our filter for the GM airbox in testing now! Dyno results here: BMS Drop in for Corvette C7 GM Performance Cold Air Intake Dyno Testing - N54Tech.com - International Turbo Racing Discussion

Good read and great data, so from the sounds of it I should take the roto fab intake off the zl1 go back to stock intake with your drop in maybe run some e20 and see if I get any codes. Maybe I’ll hit up Jesse and do a comparison on his dyno using 91 with this roto intake vs your drop in (if airbox is same as your c8) and then try dumping a few gallons of e85 in and repeat on the stock map.
