iya everyone, i have a problem my rs turbo is not holding boost, 3rd 4th 5th are just holding back alot on boost, 1st and 2cd sometimes boosts nicely only if i drive normal (30 mph) then floor it and it boosts, after that its flat like 3rd 4th and 5th, if i drive normal again 1st and 2cd will be the same as the rest of the gears flat as fcuk,

its like im only allowed to boost once a day in 1st and 2cd then its like the rest of the gears if i try it again

iv changed actuator,plugs, turbo has no play at all,checked compression,no airleaks, could it be a pipe collapsing??

any ideas people cheeRs
