You still having the problem when you first start it up of only having 8psi. I had this problem and it turned out to be a problem with the map, it was requesting too much boost on a cold start and causing limp mode, turn it off and back on and now uts fine. But now ive got another problem with the map lol, every so often when giving it beans, when in either 4th, 5th or 6th, it holds too much boost past 5000rpm and causes limp mode. It doesn it every now and again. The code i get now is 17963 charge pressure limit exceded. Back to AmD tomorrow lol
Thats interesting to know mate, I was convinced it was the map and so was Tom, but I was gonna keep monitoring it for a while and see how it goes.
It seems to be ok last few days. Maybe because its warmer now?
