I am tuning a 2002 muatng gt with vortech supercharger 8-9 psi non-intercooled. It has dark blue top injectors and 90mm Lightning MAF. it idle and drives well. except for tip in WOT. It has lean spike when pressing the throttle to WOT. It was getting to 1.5 lambda in tip in when transient into WOT. After making some adjustments to manifold volume, maf failure load and transient tables it get a little better with 1.17 lambda in tip in then the afr get to the commanded lambda. I could not find the correct data for the dark blue top injectors so I copied the Cobra data as I think it is the closest injectors in flow rate to what I have and make some changes to flow rate low and high. Any idea how to fix the lean tip in spike?
