Message	Yes thats possible. I did not understand what you ment by "saturated". Infact i agree with you, need to look at his tune to see if the maps are expanded although he was only running 18 psi but he was in add mode so.... Also keep in mind it could have to do with the max theoretical pulsewidth curve. Might not have enough headroom there. Again need to look At the bin. Harry Formerly yellowzxtt
