Congrats on the stg 2. I have the AFE Scorcher and same here you really notice the added power a lot more at 2800 RPM and on. However I am not sure how you can get 23mpg. Even 21mpg sounds good. All I been getting is 19MPG to 20 MPG being the best ever.

ANyone with 535 f10 please share a bit about the consumtion. Thnx

I don't know how you guys drive but my 535xi stage 2 barely average 15mpg. I do mostly local short distance driving which is the worst.

I like to push it here and there but damn there's cops on every corner...basically your mpg depend on your style of driving

25.1mpg!! Do you do any city driving or is it all highway? Do you ever push the car? Sport mode? I don't know how you do that but it's amazing how you get that kind of consumption with all the MODS

I have the JB4 stage 2 and get just under 21mpg. I definitely do punch it here and there with a good combination of street/hwy driving.
