ecoz strange engine problem
a mate got a new turbo fitted reciently and i was there when it was being fitted it was done right.heres the problem.when we left the garage for a blast the engine developed a miss or what appeares to be a rev limit at 4000 rpm reguardles of boost setting (16 psi to 20psi) it will even do it with the car stopped and you bring the revs up to 4000 approx.the she limits sounds like bep bep bep bep.........
if you push flat out it still wont go above this rpm even when stopped.
and its not happening all the time but it appears to be getting worse
we have changed, dizzy,crank sensor,map sensor (3 bar),plugs,leads,coil,
but its not making sence as it drove in perfect.its like hitting the sound barrier at 4000 rpm but from idle up to it and beyond it all is ok.i know the obvious thing to suspect is the turbo but it happens also when unloaded and only at one rev setting. i need the guru.s on this one

well the man was scratching his head aswell 
,i,m almost sure the lambda is back in,i didnt think the p8 was that sensitive if the lambda was nuked or missing.i melted the wires on my 4x4 saph lambda sensor and had to disconnect it and it never did that although i know its an L8 
thanks for your help
