Post some pics of my data log today. tune has defiantly changed for the better since Boost 231 supplied me with the correct OEM GM TPS ! Heard knock when I got into it @ 10 or > boost? ( By digital dash lights ) Temp is a little high also ? FP pics are engine off & then @ idle ? Should I lower FP to lessen Knock ? I"ll post a driving data Pic , tomorrow.....before any adjustments. Thanks for your opinions.
