Hi, I'm new to this forum and BMW pretty much. I recently went from a 2014 Audi A5 to a 2016 528i. I started to get the 535 for the extra power, but decided on the the inline 4 with the twin turbos because of the potential ecu upgrades. I had APR tune flash the ecu in the Audi and it gained 85 hp and about 110 ft lbs of torque. Made a big difference. The 528i is actually stronger than the stock Audi and quite a bit heavier. I think the right tune could really wake those twin turbos up, but there seems to be little or no info on the late model inline 4's. If anybody could offer any advice based on experience I would greatly appreciate it.
