Hello
I am new here and I need help
I owe F10 M5 has ESS tune, cattless down pipes, AEM meth kit, super sprint performance catback, i added JB4 stage 1 with additional 3 psi and now car hit 24 psi and drops to 22psi
Car is runing great on pump gas and made 670whp
I wanted to have more power so i installed stage 1 turbos with upgraded comperssor wheel, car is runing ok but boost can reach only 19psi now and car is slower and now its laggy about 500rpm more to hit full boost
I dont know if problem is from tune or turbos are not ok.
Any help will be appricaited
Thanks
