Ok guys i bought my evo with a bov and what seems to be a MBC under the hood,I don't have a boost gauge yet so i don't know if my boost is spiking but if i had to guess i'd say thats the problem.So here it is, ok every time i floor my car not long afterit cuts out or something and kind of sputters the rest of the way i can feel it try to correct itself but it does it every time in every gear.

 

you need a tune my friend and a boost gauge. for the time being if I were you id adjust the MBC so it loweres the boost more just to be safe. your car will be slower but shouldnt hit cut off. do you have any other mods?

 

Nope stock,ive had the car 2 mounts and cant even enjoy it.Until i get a tune could i just take off the MBC and run it stock until then.

 

yeah you can do that, or just turn the mbc down to stock boost for time being

 

just lower the boost like I said. Your prob trying to run just a tad to high. and as air temps outside cool down when you have a MBC your psi will be higher bya couple PSI. So if it was running good in warm weather but not so in cold then it is just a little to high

 

Sound's good.Umm righty tighty lefty loosy.

 

lefty loosy. the screw comes out (towards you) and it will lower boost, that all is assuming yours looks like a screw like the average MBCs do. Also keep in mind they can be very touchy so try it like 1\4 of a turn at a time. in other words turn it a little go for a test run if you still cut turn it some more and so on untill it seems to help out

 

Im picking up a boost gauge Saturday what should i set my boost at 20PSI?

 

what year car? and stock BOV or not?
