Re: low RPM hesitation and rough tip-in enrichment

Yes, please let me know of the people selling a used FlashPro. Thanks. Yeah, the stock tune definitely seems very jumpy between 1K and 3K RPM. It gets better after that. The transition between injector on/off also ought to be smoother. The throttle pedal is also too sensitive at low opening angles/R...
