hi it seems that when i use wot it will not go past 3500 and if i kick down say from 4th to 3rd (at 100km) it will jump to 4000 but it tries to jump back to 3500 max by surging hard and blowing black(too rich) but if i don't use wot i can get the rpms to 4000 (need more rome to climb any more) and then it seems to knock (too lean)
is there somthing to do with WOT
