Liam_D Posted April 14, 2013 Posted April 14, 2013 The 'bang and backfire' sounds like fuel cut to me. Quote
Greg Jones Posted April 15, 2013 Author Posted April 15, 2013 ye i think its hitting the fuel cut and its set on 10 atm Quote
Weyro Posted April 15, 2013 Posted April 15, 2013 (edited) if you are trying to run 1bar boost you will need it set to 8, but you will also need something to increase fueling you will need a boost gauge at least, to make sure you dont boost too high and destroy your engine Edited April 15, 2013 by Weyro Quote
