My friend has a greddy kit on his z6 and he made a homemade mbc and if you let ur car warm up and go to boost it creeps to 12-13 when it's set at 10 lbs. If he boost up to 5 lbs or so a couple times, it seems to warm the boost controller up and then when he boosts, it holds at a steady 10. Could this be a poor design, a faulty spring or what? If anyone has suggestions, i'd appreciatte it

 

nobody knows a possible solution to this problem?

 

manual boost controllers are picky to air density. it may just be a case of good air bad air. or maybe the spring is sensitive to heat. i dont like the ball and spring, i use an orifice with a bleed valve and dont have any creep issues with it on my friends S15 swapped 240. i shelled out the loot for a Blitz DSBC for my car.

 

I'm going to try and get a different spring and see if it'll fix my problem....worth a try

Who makes and orifice with a bleed valve?i've never heard of it

 

i dont like the ball and spring ones, get rid of it and get a turboxs one , or step up to a ebc and never have any creeps or spikes,

 

turboxs is ball and spring isn't it?and i've heard of people having problems with them. I think I'm just going to try a new spring or turn the boost down so if it does crreep 2-3 lbs ill still be okay until i can afford something better. ebc =$ which a college student doesn't have
