Run into a few more issues on the weekend managed to find an hour to get it on the dyno late sat night around 10pm. The inlet manifold gasket didn't like 18psi and made itself a nice little vac leak ouldnt expect much more from a 21 year old gasket and 230,000 km with a big turbo and some nice boost.
Looks like I will grab a full gasket set and do the head at the same time. Will also look to stick the die grinder in and give the head a port job and stick a bump stick in.
The auto realy doesn't like the boost either so need to ditch that as well
