Big Question here: what about warranty? What is process for ECU access? Drill or removal?
Also how is customer service when/if their is an issue? Warranty? Etc.. I have been through hell and back with my 550xi with 4 Different tuners. From flashes to custom ECU to JB etc.. I am simply asking the questions that I wish I asked before I jumped into the ECU tuning world of an 80k+ car.. I now have an M6 but still have my 550xi. I am now in the market for an ECU tune and don't know where to go.. I am strongly leaning in a direction but who knows what can happen in 2-3 weeks.
I am big on 1/4 track and a dyno queen lol. I am a unwrap Best* friend if all goes well.
