When I bought my bike in Spring, XL1200N, dealer put on Stage 1 HD Filter, and SE Slip On's, and did a remap for the EFI ... I did not like the sound of the SE Slip On's so I am installing the V&H Short Shot Staggered Black system, does anybody know if I really really need a tuner, or a fuelpak, some guys say I will be fine, others warn of a too lean mix ? The dealer already did a HD remap for the filer and the SE Slip on's ... do I really need a tuner ? or Not ?
Thanks
