the waste gate is on pressure not vacuum if you have a boost gauge I don't think I would go over 14 most are using a needle vale to control max boost in the pressure line from manifold to waste gate open the needle valve for less boost if you have eliminated the over boost shutoff then you should just have 1 line going to it when i find a picture I will post it

removing the locking nuts is being a challenge and the prechambers well after removal of the locking nuts on 3,4,5 1&2 will not come out soaking with wd40 now the pre chambers are to my surprise a thread size that is really uncommon 22x1.0 I found a thread size you wont believe this but a bicycle puller has the same thread size needed for the prechamber puller I bought it on ebay for 13.99 pretty cheap have the bolts for the flywheel valves are adjusted will overhaul injectors this week have my pop tester built does any one know the range for the injectors to pop off at that is the best for fuel economy
