okay so im wondering if this problem would be related to the mbc in anyway...

sometimes when im driving i can hit 20psi and hold it, but sometimes i will only hit like 17psi. also as i shift through the gears, i notice every gear i hit, i will drop some boost. so like in 2nd gear ill hit 19, 3rd ill hit 17 and 4th ill be at like 15...

im thinking this has something to do with the mbc, cause sometimes it doesnt do it, sometimes it does. and i know its not anything to do with the weather.

 

How do you have it hooked up?

 

what kind of boost controller is ???
because it shpuld be the other way around

 

its a turbo xs
and i have it hooked up correctly

im thinking maybe something inside there is dirty and its causing the ball to stick sometimes.... i bought it used off a friend for 20 bucks, so i cant complain. i think ill take it apart tomorrow and see what i find

 

Oh my gosh... did you just said Turbo XS? is it the little tiny blue POS, it is the one that needs the allen wrench to ajust from the top right? . Get rid of it ASAP. I had it on my WRX and gave me nothing but issues. Get yourself a Halman or a Forged and you will never had issues.

is your air conditioning on when it happens?

 

no its not that one your talking about...

i will eventually get another one, but this has to do for now...
im tight on money at the moment

edit:
it does it with the air on and off.... i dont think its the a/c causing this

 

Id tell you about my experience with a turbo xs mbc but Id rather just quickly tell you to get a hallman and sell the tbxs on ebay.Once I switched it was like seeing the light.
