hello guys im not really a regular user of pf but im running out of idears with my frst basically its got this fault under hard acceleration or at 85mph it sorta cuts boost momenteraly and then wont let you boost up
ive had it looked at so i know its not overboostin so i took it for a tune and a fault check done it came back with the bpv (boost pressure valve)(amal valve) so ive now bypassed the amal valve and the fault is still there i was told that when i bypass the amal valve i will need to refit my 165 superchip so ive done that so it should have ruled out overboosting because of the amal valve not being there. but its still playing up

if any one has any idears or had any similer problems i would be most gratefull

cheers guys

dave
