I have got the Z booked in on the rolling road at John Noble next week. The new engine seems to be running very well...

 

But every single time I go full throttle the boost maxes out and hits the limiter on the pro spec 2, as soon as this happens the power drops off and clouds of fuel come out the back.

 

I have tried turning the pro spec 2 right down but it still hits the limit (12 psi in low mode), just takes a little longer to get there. Its fine at 3/4 throttle just not full, every time.

 

So...

 

Its going on the rollers to be setup by the pros

 

I'm just hoping its not a leak or rubbish actuator causing it

Other than the obvious, is there anything I should do or check before going as this will be the first time I have taken a car on the rollers

I'd check the TPS settings mate. Make sure you take a Conzult with you. They may not have one.

Yep did the tps the other day, got it at 0.44v at idle (was 0.66v when checked with consult at zfest)
