Just a quick question
I remember reading some ones project thread back along and it sating they were running 22psi on an xud . They then fitted a full straight through or 2.5inch exhaust cant remember and they reckon it freed up power and was then boosting higher due to just changing the ex system.
Is the standard xud exhaust that restrictive or not.
All I have is a backbox. And I still cant get over 22psi is this the reason
Cheers
