Re: 1st Run on Datamaster LOTS of Knock Retard, Please Help!!
Yes, the stock turbo will make 21psi.....the stock turbo will make 121 psi, though many metallic things will come apart long before it reaches that.
21 psi on pump gas with 136degF IATs and 11/12:1 AFRs.....it's actually surprising that it was ONLY 7 deg of KR. The AFRs show you running lean, so add some FP and see if the KR goes down. Most of my 3 bar chips to best with 45-50 psi of FP at idle with the vac disconnected.
And no, I don't tune anymore. Tony Hyder's Typhoon was my last. Got my second child on the way and my truck still not drive-able, so no offense to anyone, but I "gotta do me".
