Too much boost!

Took my car to sheffield to work today.

 

on the m1 on the way back i had a little play.

 

with greddy pro spec 2 on hi, in 5th gear at 70mph foot flat to the floor

boost hit 16psi before the controler cut it out at about 110mph

 

WTF? I had it setup perfectly, could take it to the red line in 3rd and would reach about 14psi

 

but in 5th it just keeps climbing

 

I then set all the hi settings to the same as lo thinking i would get about 10psi like i do in low mode and it would sustain it

 

but oh no it just keeps climbing, 16 again, just took longer to get there!

 

i dont want that much boost!

    not good when the controller cuts the boost tho as it feels like a missfire / major F*%kup

     

    better than going any higher tho

    Sounds like your duty is set too high and the gain is set too low. When the controller is set up properly the boost should hit the target value fairly rapidly and stay there...

    ahh, yes i didnt turn the duty down as its selected by turning the knob only, forgot about that.

    Thank **** for the warning feature then ;) Good lesson to everyone else with EBCs - make sure your warning is set to a level that is safe for your car, PLEASE! Safety features are there for a reason! I know quite a few people who would have just turned the warning level up to stop it 'hitting the wall' and then its bye bye engine...

    i turned my limit down from 15.5 to 15 before i put this post up, would rather it cut the boost than blow the engine!

     

    just got to turn the duty rate down now
