    Yes, Not sure how you run the engine, however, Your highest torque and HP was at 1380-1400 rpm range with good boost. which is the sweet spot for fuel savings.

    Blow by was fine once under a load. If you have concerns pull an oil sample after 8-10k miles to give you a better understanding about the internal wear parts/points or antifreeze issues

    Well I hope you didn't pay for that one. 5000 ft torque with under 400 hp. Not happening. Did you pay for that? The tech should have said WTH is wrong
