Help Please Stuck

[Guest cheshireglanza]

got external wastegate with screamer pipe plum it from turbo to one off the ports on wastegate boost's all over the place,plum it in into other port it boosts at .3 bar only getting two green boost lights on dash holds back what can it be

[string]

boost hose goes from nipple on compressor housing to bottom port on wastgate. top port is left to vent. thats how its ran if ya using the wastegate spring pressure. wht spring do you have in? is the wastegate fully welded up? does ya ext w/g open at .3 and scream/ safe

^^ if i plum it in that way its boosts all over the place

What do you mean all over the place?

[Guest cheshireglanza]

its boosting well over bar lol only 5psi spring in wastegate

[lukEp]

You mean .5 bar spring mate

[Dean @RW-Developments]

i know exactly what you mean i did it with mine by fitting it to the top nipple it basically bypasses the e/w spring pressure allowing it to effectivly to boost how ever high it wants? on my car it was mental fast the only thing that was stopping it boosting crazy was the factory fuelcut.

if you fit it to the bottom nipple and leave the top 1 venting to atmosphere it will run at spring pressure and at 5psi it wont be all that and the screamer will sound like its falling asleep lol a bit more boost and it will come to life and the screamer sound will completly change

hope this helps
