Let's talk tunes for the M40i
Just bought a 2017 X4 m40i as my baby M. I also own a 2014 M5 with a dinan tune. Take to me about tunes for this engine. Gains, reliability, etc? Maybe its too soon to tell on the reliability side. Dinan's tune really looks like its built for the 3.5i engine to get it up to m40i output levels and even though they sell it for the m40i it looks like very small gains no?
What else? MHD? Mission Performance? I have 2 years of CPO warranty so that's a consideration too. What did you go with and why? Thanks, Jon |
