i have a apex with new 290 kit on it, installed in feb 09, came set up at 14psi. it has the aux fuel pump also. Now my question is, can i turn the boost up a bit like 16psi without doing anything with the kit itself? will the mcx box just readjust the fuel accordingly? Do i need to get the box reflashed again to run 2 psi more boost??This is the newest 290 kit i was told for when it was installed. i could tighten the wastegate rod 2 turns and it should be in the ball park. I know i need to run better fuel at the psi also. anyone???? thanks in advance D
