Would anyone happen to know what the max HP & Torque gains are for my 2017 F15 sdrive35i N55 engine before you need to upgrade the intake and exhaust?
I'm thinking about doing the Racechip RS but an increase of 75 HP & Torque seems like a whole lot of pressure buildup in the cylinders with the factory exhaust which seems like a great way to blow a gasket or rod. I would appreciate any advice. |

Just stock all round. The power increase is most noticable in the mid-range, but it isn't like you've added a second turbo or anything dramatic. I will say though that when I take it out if the car is booked in at the dealer, you suddenly feel like you are going so slow! As to mpg, I didn't buy it for that so haven't really paid much attention to my numbers. Problem is, since I 'm working from home now I don't get to drive it much so when I do, it's with a heavy right foot

Not too bad. Personally, if mpg was important I would buy something smaller/lighter/diesel. Eco mode drives me nuts as you lose the immediate pedal response. To my mind it's a BMW and it's a driver oriented car (I know, even though this is an SUV ) and should be driven as such. Eco mode should be banned in BMW's!
