From what I'm reading in various SAU threads the boost solenoid on a RS4S bleeds of boost that is higher the ~7.5psi, and this is controlled by the ECU.
My understanding is you can
A) Get ECU management and tune it out
b) Install some type of boost control
c) Earth the solenoid out but run the risk of infinite boost, (but u can remove the risk by installing boost control?)
I have a TurboSmart duel stage boost control, and when I try to adjust the high boost with 1 or 2 clicks up from 7-8psi, I get a hesitation and it doesn't boost past 7psi (which I now think is a boost bleed off, not coils) As I have duel stage boost control is it safe for me to earth out the solenoid?? I really would like to run 10psi maybe even 11psi..
I would really appreciate if Rs4s owners could let me know if you experienced this problem with boost past 7psi and how you manage it. Or even if your RS4S had this issue
Thanks heaps and for all those that have helped out with my recent posts... You rule =)
