Adjusting Actuator on HDI 90

[hywel30]

Can anyone tell me how to adjust the actuator on my HDI 90 also where to tap a adjustable boost valve into????

It won't make any difference, as the boost is controlled by the ECU. At best the ECU will try to compensate for the adjustment to put the engine back to the equivalent of base settings, at worst it'll run like a pig.

If you want to adjust settings like that youll have to and get the car ECU remapped.

Thanks mate, any idea how much a remap is?? and also iv'e just fitted a boost gauge and it says it's pushing 15PSI, is that about right for standard??

most car performance places will do a ECU remap or know someone who does but isit really worth it 15 psi sounds about right as thats around 1 bar of boost which is plenty for a standard turbo
