boost pressure

[TALONFACE]

First of all I have a dejon tool dual stage boost controller, and it set at stock boost which on my car is 10, and high boost is 15. My problem is when i switch between them, there is not much difference in power, but there should be a pretty noticable difference, and my boost gauge reads 10psi, and on high it reads 15psi???, and at high boost the turbo seems to flutter abit?. You can check my profile for any info on mods!!!! Can anyone help please?/???? Thanx

Have you done a test on the piping to check for leaks?


There is more power, it might not shove you back in the seat with the 14b, it just is not as noticeable as say someone using a 20G and going from 12psi low-to-20psi high.

Sounds like it is doing its job then.

and at high boost the turbo seems to flutter abit?.

Little bit more info on this.....


Is it at the switch or if you are driving the car in high mod constantly?
