Hello guys I hope that I might be able to help,now are months that some of resolve in vain, this problem. About a year ago I bought my 147 1.9 150 2008 with the dpf. After some months, appeared to me to be the fateful error p0091,this happened to me with the original map. I took the car in for service and I have overhauled the high pressure pump,or at least so they say you have done it. In the meantime, I made some changes: removed the catalyst, the initial and dpf, fitted an intercooler at the front with pipe in silicone. I did prepare an online map by a well-known site of processing units, and after having tried the machine I reappears the same error. The preparer, or if it want to call it, told me that I should put back the original map and fix the problem, but with the original the problem does not occur.
So I armed a lot of patience and I have modified the map by activating the dtc that I had disabled, and by making the switch off of the fitting.
The car drives fine, but if you are fourth about 2500 rpm and thrust the pedal, and around 3000 seems to be a hole of power and then I get the error that sends me in the recovery machine.
Today I disassembled the pump low pressure in tank and cleaned out all the dirt even if it was not much, I try again to move the car and the error reappears. Another detail is that the machine is struggling a bit to get in the bike, no part ever in the middle of the shot. the only thing I have left to check are the injectors.
If you please you may give a look at the map if there is something abnormal.
here are the maps:
