Hi folks, I have a v6 silverado with a 5spd and just installed a vortec supercharger kit from an older s10. I run a 12:1 fmu on the stock injectors, with a water/meth kit that I've yet to hook up (haven't gone over 6-8 psi yet).
When the engine is warmed up and driving around for a while, if I put about 70-80% throttle in it, and the boost goes up to about 6-7 psi, it throws codes P0101 and P0106. The motor bogs and it acts as if it's hitting a speed limiter.
I was browsing around on my HPT, and found under engine diagnostics/airflow there are settings for max MAP and MAF readings. Do I simply need to start with tuning for the fuel trims and disable the MAF (found a real good how to on this website). I'm guessing it'll correct this problem?
-> Also, I didn't order the fancy HPtuners that can log my wideband along with the rest of the HPT sensor readings (it's on a separate data logging software that came with the LC-1). This might be a dumb question, I'm having a hard time wrapping my mind around how tuning the fuel trims or VE table can affect my AFR... I mean, how can driving it around as it is right now and collecting data for the fuel and filling in the gaps richen up the fuel system?
Do I need to gather the log data and then make the overall fuel trim table some % richer than they are now and kind of guess and check till I lower my AFR? Again I'm new with this so if you couldnt tell...
AFR is at a steady 14.1-14.9 now and the goal is around 11. (just took the AFR reading today so I'm not going to be boosting anymore with it being this lean)
