Have you adjusted the acceleration enrichment? Can you tell if it's a lean stumble or rich stumble?

If it is a stumble, then it is most likely lean. What does the wideband say?

Also, remember that the base fuel map must be fully dialed in before acceleration enrichment is adjusted.

If you want someone to do remote tune for you las Vasquez has a good reputation on yellowbullet. Not sure what he charges.
