I have a 2018 jaguar XJR 575 and have had a few upgrades done. The issue is when trying to remap the vehicle the supercharger can only make 1.9 bar of boost, the supercharger should be able to get 2.1bar or 2.2bar but mine just won't go above 1.9 bar. Any one of any ideas why and how to get above 1.9bar
