@LencTPH - No sorry i dont i had it logged at GotBoost in Bridgend. And funny enough i had exact same problem first of all and we found out i had a lazy fuel pump. So i had the fuel pump & cam follower changed with new and the fuel loggs where then perfect, the Turbo pressure loggs where peeking spot on etc etc.
The fuel pump loggs where something like (sure someone could do this better)
At idle it was something like -0.5
Full throttle it was hitting +59.6 but slowely droping down then to +12.67 then to -1.34 something along the line of that if it makes any sense??
And once the pump was changed it was something along the lines of -0.3 then throttle +23.9 then drop straight back to -12.63 etc etc
Hope that makes sense to you or to someone that kind of knows what im on about hahaha
BUt in the end of it all we found out the Ecu was sending the turbo (such) pressure and the turbo was then regulating it blah blah
