Re: Stuttering under boost
I had similar symptoms and it turned out to be a broken wire to one of the injectors. At least I hope so, because I have just finished fixing the wire and I will make a test drive tomorrow

Ok so checked various things to no avail so what i have noticed is in 3rd gear when i reach 3k revs it stutters for a few moments and then accelerates normal and does the same in 4th and 5th ?? Any help would be great

Check your ht lead connections! Could be those, I had a similar issue where mine died at 3k!

The High Tension Leads; From the distributor to the spark plugs, and from coil to distributor.
They suffer a lot on the turbo due to under bonnet temperatures, so should be swapped out for new ones every couple of years.

Found the problem was head gasket and compression blowing into the coolant ' ie stuttering' no water in oil and only realised when checked coolant reservoir and bubbles galore
