Audi You Do Posted February 18, 2020 Share Posted February 18, 2020 Recently fitted a boost gauge to my a4 1.8t BEX engine code and ive noticed the peak boost is around 15-16 psi and it settles down to around 10 psi, is this because it is a BEX 190 do they run higher boost that the usual 7-8 psi i hear most standard 1.8t's run at Either the BEX 190 is higher boost standard or the boost has been turned up i have seen when tuning people set the max boost at 1 bar just below 15 psi so im thinking the car must be remapped Anyone got any ideas whats going on thanks Quote Link to comment Share on other sites More sharing options...
