wondering if anyone can help. on my bro's rst the car will only boost 4psi. then floor it again still 4 psi. come to a round about large it in seconds holds 14psi like it should. came to the next round about and it will only boost 4 psi again tried a new -31 still no good. any ideas???

How's it setup ? Does it have a 2 stage boost control on it ?

 

it has a chip'd ecu. from a mates car that was running fine. he still had the problem when running standard boost and chip.

 

boost leak

 

Is the amal valve plumbed/wired in properly

 

if it runs 14Psi sometimes and only 4 other times IMO it is prob something to do with the wring to the amal valve or the amal valve itself that it fooked.

 

I'd say amal valve is the 1st place to look!

 

lovely i'll give it a go! thanks alot for your help
