I drove the diesels!

19.5psi did u strengthen ur internals b4 you did that

No, it's still stock inside.
It's safe at 19.5. Big injectors.
cold water inj, cool intake charge.
It's tuned right, and that's the key. Lean enough to make 198kw@ the wheels, but not so lean as to have issues with pistons etc. The guys at Air Power Systems in Melbourne and Con at CV performance are the only people who will ever tune the car.. Trust your tuner and a 12 sec pass is a reality. I run 18psi and a different tune in summer, which results in much lower numbers.

good stuff! ive heard of too many people boosting the turbo PSI and not thinking bout the extra stress the engine has to bear! and it ends up blowing up...
im glad that youve got a pro tuner onto it mate. love your car
