Guessing having the header ported and a slightly larger exhaust makes a difference.
What has me confused is a couple of members with TOR exhaust ran the tune and did not stall.
Only time I had stalling issues was running lower octane fuel with ethanol.
kevh, try the forced adaption. Start bike, wait 13 minutes. (don't touch anything)
If it does not work, try Soltec's and AK's tune. Run what works best.
