In relation to YOUR Logs.. not millars, 4bar FPR is a crock of **** reply.. The MAP REQUESTED fueling, as per your logs is standard, and LEAN... Adding a 4bar FPR is not the fix.. It will simply force adaptions to back out 15% fueling as it will be too rich, but STILL only fuel to stock 0.9x lambda under boost. MAP is your issue... they did see yours logs did they not? dont fit 4bar fpr. it will not fix their incorrect fueling requests in their map.
