Ask me any other questions you may have, I may have abandoned the build but I did spend countless hours reading and doing research on boosting the 2.8l engine.

No, Ive abandoned the build. But to to this successfully you will have to use a stand alone ecu to use the MAP sensor (reads boost pressure) instead of the MAF sensor. If you get on to SCaudi.com there are tons of people who have used the m62 charger on these cars without doing a stand alone ECU. I just wanted to run more boost than what the MAF sensor could handle but I want the car street legal.

Did you manage so sort ecu issues when supercharging 2.8 just bought an m62 myself but it needs rebuilding before I attempt any conversion
