Im looking to go back to a MBC but want to retain my 1/4" tubing lines. The turbosmarts and hallmans seem to only be 4an (7/16-20) threaded holes. I cant find 1/4" push to connect fitting in that size, so are the any MBC's out there with 1/8" ports besides the ebay brass tee specials?

The hallmans the one i wanted and am willing to machine some fitting to make it work. I just cant believe that when all EBCS are 1/8 npt, that noboby would make a 1/8 npt MBC

i was ale to run a 7/16-20 die over the 1/8"npt thread relatively easy, it jacked up a couple threads but for the most part i think its doable.

Im gonna give this ebcs one more shot on the lighter wastegate spring, if i cant get it consistent them im going MBC

sorta. It spikes with the inline valve, but with the lighter spring in the EWG, its spiking below target so in theory i should be able to use WGDC to get it to flatline at target, in theory. I really want to get it to work since its flex fuel and i want the ecu to control everything, but i only switch fuels by season so its not a big deal if i go to a MBC. But MBC does do away with any types of boost cut safety

What inline valve are you referring to?

Can you not do hybrid boost control so you have the benefits of boost cut safety, per gear boost control, etc?
