Can you do a log of blocks

115
114
060

then you can see if its a hardware issue

i done some logging just driving around, i would have to go to the motoway to do that, so many little kids around at the mo.    I live next to the beach.


have a look over the log above

I am looking at them now, the load in the midrange is a constant 20% over even with the N75 map pulling back to 70%, its hard to see from the logs but it look like the throttle plate is trying to cap the over boost as well.  This is the problem with custom mapping its very hard to get it done in one stint all tuners get these issues..  You have two options, one is to reduce the pre-load on the actuator to see if it brings the boost in to requested range, or just ask AMD to reduce the  KFLDIMX (N75 I polit map) between 3200rpm and 4000rpm by around 10% of the actual N75 value, and it should be about bang on.  Apart from that the requested values look spot on.
