Its a typical euro-5 engine ISX. They use internal EGR via an altered combustion cycle instead of an EGR valve and they also dump raw fuel into the exhaust (via injection pulses on the exhaust stroke) to keep the SCR unit clean every so often instead of having a DPF can.

95% chances are in favour of it having a horrible program in that ecm, most people who make those so called "tunes" are nothing but brain butchers who have no idea how these engine run, only block the fault codes from showing up in the dash, and it simply fools the driver into thinking everything is ok. They torture the engine internally, causing a severely shortened engine life.

Copy the program out of the ecm and send me a copy of it. that is your first task. Find out what kinda program someone has made and stuck in there.

NEXT: You need to adjust that wastegate and drop that boost down to about 36 psi or so.. 40 psi is too high for that engine with no emissions controls on it any more.

Is the SCR guttered out?, or a straight pipe installed to replace it?--- if not then that also needs to be done.. That SCR is going to restrict the exhaust flow and clog up after a while if it has a de-mandate program in it... as it can no longer keep itself clean.

Thank you rawze ill get a copy out and to you today. Pipe hasnt been done as yet. In the process of finding another one to gut so not to destroy the original.
