So what would need to be changed on a 2015 to get the same updates as a 2018? ECU, suspension, blip shifter, brake calipers, brake master cylinder? You know where im going with this. How much stuff was actually changed and did it significantly increase its stability and control or smoothness of engine? As far as i know nothing internally changed in the engine correct? Head is the same? Im installing race cams now and with this added power i would like to have added stability and control/ braking power.
