Stumbling on boost

What would make a turbo stutter under boost. Put your foot down and it takes off nicely, then stutters, then kicks in again.

Have checked vacuum lines, so could it be fuel cut off or boost control solenoid!

Have had it on a couple of turbo vehicles in the past, any ideas!

Turbos don't stutter, but engines do. Check your spark plugs, HT leads and fuel pressure to begin with.

Thanks for the reply Mugen.

Could a dodgy cap and rotor cause this effect by not getting the spark right on all cylinders!

Sorry, what engine are we talking about!
But, yes, it could do, although, faulty rotor and cap would create problems at all times.
