I have an '05 B model that recently had an SE tuner and thunderheader exhaust installed. Since this I have to "baby" it while its cold. If I get into the throttle it will hesitate, pop/crackle, until I let off the throttle. After about 20 minutes of riding it seems to dimenish. I have an appointment on the Dyno at my dealer on 7/13 (at N/C), but, wanted to get some insight... I have read some of the posts on EFI and how it works.... Am I correct in assuming this can be tuned out???? Thanks for any input!
