tune above 10psi
Ok so you guys have been a huge help so far so i thought i would try again..
My turbo has been played with a ruined.. (to4 front cover without changing wheels or anything) so it doesnt hold boost at rpm well at all so currently it will hit 9 psi and come down to around 7 but i would rather 12-13 psi and come down to 7 a it pulls alot harder.
So 2 plans of attack.. would upgrading wheels in stock s5 turbo work or better off with standard front cover on turbo would be happy with over 10psi at redline. not using standard wastegate got 44mm Tial.
Problem:
Tuner didnt tune above 10 psi so above that it leans out... which is stupid because boost cut is 16psi so if something failed and freeboosted it would lean out. so need to know how to adjust map for that boost
Engine is extend port. 500hp Bosch pump 550/660 injectors, full 3inch exhaust etc.

ok changed the map and no more lean out actually goes rich as so have heaps of fuel so will take a little out.. gonna keep a/f round 11? and sometimes it stutters a bit but that may be the voltage? alt belt pretty loose havent tightned up yet a was only on 12.5 volts.. but a couple runs up to 6.5k rpm and went smooth as just real rich
