ok well i put iit like 8 degrees an is fine no any boost bug at 4000rpm

but i also put my fuel pressure back because i had to mutch pressure that at the black box on the meetering unit i had a fuel leak
now it s ok no any more leaking

but now i have only 12.3-12.4 on AFR when i drive it also on boost it s 12.3 some times it hit the 11.00

before i always had 10.5 -11.11

is it enough safly with 1.4 bar turbo boost ?
