White phase 1, now with added truck turbo and massive head gasket failure

Looks to be quite laggy from the graph? Still personally think the hotside is too big, if you had the engine revving to 6krpm then fair enough but it doesn't look to be at peak boost until pretty much 3krpm.

Was this not a twin scroller too?

And as said, don't worry about an 11mm until you can get it boosting clean.

It certainly does need more revs to get the most from the turbo, gov mod is on my to do list. it is a twin scroll yes, starts spooling quite early but the revs cant build up fast enough to get it boosting hard until about 3k.

il make a vid of it on boost, fiddled a bit with the pump when i got back from the dyno and it seems to be clean on boost now
