what is the highest boost that is safe anyways? i no that over 35 is pointless on my hx but i've seen 42 for a split second. explain more on this vice grip thing...i need cooler egt's bad

 

Does have to be vice grips, just anything to pinch off the hose going to the waste gate actuator. I threaded a set screw into my hose when I had the waste gate on mine. Used a couple zip ties, on on each size of the screw, to make sure it couldn't move around.

 

I was just sayin vice grips to test pluggin it off but my waste gate is plugged and the shaft is way shortened, the latter is when I noticed the biggest drop in egts

 

the ECM defuels +/-19psi stock. you'll need a programmer or box that "fools" it to get more.
you increased the pre-load on the gate. gates do not just "pop" open, they open slowly as the drive & boost increase. by shortening the rod, you increased the spring load on the puck and now it takes a little longer to move it. the only downside is IF you were over-boosting you also have less puck travel now, so the gate wont bypass as well.

 

If there was a better gain with a shorter rod over the plugged hose, your gate was open, or opening too soon.

 

i already have my line pinched off i was talking about the original post about twisting the shaft or whatever? but wats this about shortening the rod? how much did it lower egts and what are other benifits?

 

yes I had my line plugged originally. What I would recommend is pulling the turbo off the truck undoing your shaft to the waste gate loosening the nut and screwing the end part down maybe 3/4 of an inch. You will have to pry back on the pin but it was worth it to me. That's what I meant by shortening the rod I just scewed it in. seems like way quicker spool time 2 more pounds of boost for me and lower egts.

 

I just finished putting a turnbuckle on mine. Went from 22 psi to 33 psi and EGT's seem to be much cooler
