2006 Saab 9-3 repair Question turbo

T8 engine management does not support external turbo boost increase mechanisms ,only way to do safely is to purchase a after market engine control unit [ecu] ,putting on a external boost mechanism with out increasing fuel intake also will cause engine internal damage [detonation ] burnt pistons ,so sort out a after market ecu ,if u buy one u will need to take to dealer for install using there tech2 to mate unit to vehicle system. good luck ,check talliaferro imports .com [genuine saab.com] they have all the toys u need to increase boost safely.
