FP3 and cams , jerkyness after auto tune
Hey guys , Hoping for some opinions . I've been working with V&H on getting my map dialed in just right for the cams I recently had installed . After I did approx 6 hrs of auto tuning , I uploaded the map to V&H for viewing , they said that it looked great , but made some minor tweaking and sent it back to be flashed .
Yesterday I got a chance to see how it would perform , I gotta say " wow " , performance is awesome , and it runs better than it ever did before . The only thing that bothers me is the slight " jerkyness " I feel when slowing down from 3rd , 2nd to 1st , not braking , it's minimal , but still noticeable . I spoke to them about it and they suggested to leave the map as is because the parameters are at where they should be . I know this would make slow manoeuvring in parking lots etc , a bit of a challenge .
so , question is , will this improve after I ride for awhile , something about the ecu learning the new flash , or could it be something else causing it other than the tune , had a new se compensator installed as well , so maybe the chain to tight or --- , bike was super smooth before the cams were installed .
I was planning on getting the bike dyno'd with a tts , but not this year , hoping to use the FP3 for a bit .
Little info , 10 Road King , Arlen Ness Big Sucker , Woods TW222 Cams , SE Compensator .
Going to be working today , but will be back later today . Thanks in advance for any opinions or advice .

Thanks for your responses guys .
I have my idle rpm set at 1000-1025 , not sure I would want it any higher . The cam lope does sound pretty wicked with the cams I have , but I'd rather have drivability over sound .
I have it set at " Aggressive " , but this is definitely something worth setting back to " normal " and seeing if it helps , never thought of that . We just had a cold front move in , snow/rain , so testing out that theory will have to wait . Before I did the cams , I had my Stage 1 map set at " Aggressive " and it worked out awesome , but with the new exhaust and cams , it could be to much . I'll give it a try .

Something I should mention , during my autotune , the map was set on " Standard " for the throttle progressivity , it was after I had finished the autotune that I changed it to "aggressive " , which makes me wonder if that's the reason I'm getting the slow speed jerk . I've changed it back , now waiting for better weather to do a test ride .
I honestly don't see how changing the progressivity after an autotune would cause this , but I'll give it a try , I'm definitely no tech expert , lol .
I'm also wondering if it would be wise to rerun my autotune using this exact map to see if I can improve the lower rpm range , 0-10 % throttle . I know once the cells have been set to green , there's no improving that area . Maybe an hr or so of slow speed , stop and starts would help , but I'll contact V&H before I do this .
I do have plans on getting the bike dyno'd with a tts , which is something the indy recommended when I had my cams done , just wasn't in my budget at the time ( last fall ) . I was hoping that the FP3 would do until fall or spring next year , but if I can't get this to improve , looks like I'll be booking it in .

Update , yesterday , I changed the throttle progressivity back to " Standard " , at the same time , I checked for error codes , it came up with 2 , front and rear cylinders running rich . I know that these errors were not there before the autotune , so I cleared the codes and will test ride tomorrow to see if the jerkyness and errors are resolved , if not , I'll contact V&H to see whats up .
