Mhd stage 2+ questions

[Sawvyeej86]

Hey guys!

New to the forum but I've have my 335i n54 for some time now. Finally decided to modify it. Currently it has fmic, dci, muffler delete, vrsf downpipes, and chargepipe, mhd stage 2+ in 93 but going to reflash e30.

At idle my boost reads -8 to -10, and at wot it climbs maxing at about 16. I've checked all vac lines and IC piping to ensure no boost leaks. Does this seem right? Will post some logs real soon. Thanks!

Well at idle you have vacuum, not boost. Why do you think you have a problem? I see 18psi at WOT, but I'm N55 on stage2+ 93.

Oh right, I meant vacuum. The car drives great and feels good. It doesn't have a rough idle or anything and the power delivery feels good. I've seen people hit 18+ lbs so I just thought maybe I may have a leak somewhere.

Well if you didn't have vacuum you'd have a problem. Not sure your problem, are you asking why you aren't hitting 18+psi ? You sure your current map should be hitting that ?

When I had the stage 2, 93 map I was hitting 18 psi, but that was when revision 5 was out awhile ago. I heard they are on revision 8 now ? Could be targeting different boost ? Dunno.
