Thought I would update u for ur own knowledge on the patrol I have not had a chance to load the new tune I have just been running with the bypass plug and after driving it for a while came up with what I think has been the cause of my problem and it’s not the chip the turbo is spooling up too early and the chip is only magnifying the problem I adjusted the turbo and refitted the chip and it seems to be much better I thought u should know this thanks for ur great service and sorry for blaming the chip
