fellow board members, can anyone please recommend a good dynojet powervision tune for a harley 2012 sportster 883cc upgraded to 1250 w/ vance hines 2-in-one exhaust and K&N 63-1126p air intake?

 

Hi from the UK and welcome to HDF. Have you contacted the brand that made your 1250 kit? There are plenty of 1250 owners in HDF and they will want to know which brand of kit you have.

 

grbrown gives good advice. Your engine kit vendor will know what tuning his kit needs to run properly and avoid damage. Getting your tuning instructions from anywhere else puts your engine kit at risk and may void any warranty they provide.

Typically the kit installation instructions will contain directions for tuning. So that's where you should start. Then if anything is still not clear, you should contact the kit vendor.
