Hi all - Most of you know the fun I have gone thru with getting my car situated with tuning especially after the Mace Cams install and then the IPF install... My tuning is now in the care of Performance Race Solutions of Sanford, FL. and they have been great... Mike and the guys put a lot into getting my car where it is putting in 20 plus hours of dyno tuning into it after righting some wrongs after IPF install... I would highly recommend them to any LFX owner in the area looking for a tune, they do all kinds of cars-lots of DI cars... I'm currently going back on Thursday for wideband/boost gauges upgrade and installing larger 1000cc aem meth nozzle and more dyno time.... on last visit engine starting going lean at 5500 and by 6800 was too lean on 100% methanol... there seems to be no issue with fuel getting to the engine on stock tank pump but hpfp not letting it in... Ive been searching for a way to improve and further safeguard the fuel delivery so if anyone has any recent info that would be great... I was flirting with idea of upgrading valve spring set and spin it closer too 8000 since this combo showed a steady increase of power all the way thru, but with fuel restrictions no sense yet!!

What lambda is the target?

Based on 100% gas AFR? I ask for Lambda because it is a true indication of how much fuel is left over for cooling. A 13.8 AFR based on a 14.7 AFR is 0.89 Lambda, which is right for a DI engine.
