Just checking in to see if anyone has any experience using HPTuners on 99+ XJs? I'll be building a supercharged 4.0 at some point and was looking at options for tuning. I know of the Split Second setup but already own the HP MPVI2 and would prefer to flash the stock ECM depending on what all is accessible via HPT.
Thanks!
