basically ive got an rs its been "set up" allegedly for 10 psi i put me foot down and yes i expect lag BUT it seems as tho its holding back and wont boost fully never seems to get to 10 psi on the boost gauge

ive been told that its the ecu not allowing it to boost more than standard so would buying a chipped ecu work ?

or is there anything else it could be? im also breaking an rs s2 so ive swapped the ecu's over and seems to have made a bit of a difference but not a great deal

or could the turbo be gone?/ going?
