I have a snort stg3 kit and am using a bleeder boost controller, lately i i tryed tweaking it from 10psi up to 15psi and everytime its hits 15 the quickly bleeds back down to 10. Any idea as to why, i have check for leaks and not found any

Maybe the diaphragm in the wastegate has a small hole???? Prolly something really simple. I dont think the bleeder type controller are any good for higher boost pressures?? I am still learning..........

The bleeders should be okay at higher pressures.

In the AU I had, I had the same problem and it ended up being a dodgy turbo. Some of the fins were damaged and it couldnt sustain higher boost levels. An Eboost fixed it though before we found what was causing it.
