Would it hurt if I reinstalled the old chip to rule out potential problems? I would not get into boost or go WOT, just cruise it to see if it improves the rich condition/sputtering/etc. I think my problem may be because I'm not getting any data from the powerlogger and I can't set the afr or select which wideband I have. Am I way off on my thinking here? Any thoughts? The old chip is for 009 injectors with no engine mods and I'm running 60's now with ported heads and bigger cam. Still ok under light throttle or bad idea?
