i twisted my halmann MBC, and it is not a click type of mbc, so i twisted it back pretty damn close to where it was, give or take 1/2 a centimeter. I have a a defi boost gauge, and control unit. Will i be ok? If not, what can i do to correct my mistake?
Drove it today and felt normal, but the car is new to me and im not sure if it was tuned for 21 or 22psi.

 

Dude, didn't you post this in the MBC testing thread?? You will be fine...haha...21psi is fine even untuned. Since you just bought the car I would have the tune checked out anyway...

 

yeaa i did.. double checkking though
thanks for replying again. what changes when i open or close the mbc, that i can see on my boost gauge? for example, does my idle change etc..

 

You should be fine. Your idle will not change. Just keep an eye on your boost gauge and A/F ratios if you have a wideband.

 

roger that.. double thanks dood.
