boost jump?

[island03gst]

Just wanna know if anyone else has this problem and what it was that causes it. Finally got my car fixed and raised to the boost to 15 (was at 10) and i notice that whenever I accelerate, the boost climbs smoothly to 10, stops there for a second then jumps straight up to 15. I thought it was just the gague but you can hear it from the turbo. Ive tried playing with the boost controller and checking all the boost lines but i got nothing.

Mine does the same thing. Wondering the same question. What kind of turbo and boost controller do you have? I have a small 16g and the profec b II.

Are you running your mbc off of your compressor outlet elbow or your bov? Try switching on whichever you run off.. Also make sure there isn't any little cuts in your mbc lines.

the greddy pfofec you have is a great BC but can also be very detromental if you dont know how to set it. you have boost spike and you need to set the gain and the set gain value further apart (it says that in your manual )
