Ive been told that a ECU upgrade is the last thing that should be installed to acchieve maximum performance with the new programming.Makes sense to me. Is that true.Does anyone have tons of mods and then have a ECU programmed for them. I want to know how big of a difference its made. I'd think that it would make a huge difference because the Max is almost fully controlled by its computer. Let me know what you guys know. Thanks
