Phase 3 Overboost

[jackb77]

Hello I'd like to know how set max 1,5bar overboost with my ph3.
I close the wastegate and turn the nuts 4 times (4mm) like the TIS Opel reccomended.
After this I set the spring with a little (very little) tension.
Please help me, I don't want to lose an engine becouse the instruction are too vague.

set your overboost in 5th/6th gear

How I set? With the spring?

 

[CallyTurbo]

yes, with the spring or get a -31 actuator and don't use the spring at all

 

[jackb77]

Ok my overboost in 6 gear is 1,5bar, but the turbo can't held more then 0,6bar at 5 and 6 gear!!!!

you might need less tension on the spring and more tension on the actuator. i found my car held boost better without the tension spring

With the actuator of EDS can I held 1,25 bar and 1,5 in overboost without the additional spring?
I want upgrade from ph3 to ph3,5 but I think that I need a new wastegate

Yes !

Get the one from EDS,

myself and 2 of my mates are driving them,
without any (boost)probs

This is adjustable?

Regal have one 8-10psi (and one with adjustable spring that hold 16-18psi (1,10-1,25bar)
The actuator in Eds website seem to be the first one...
