Not sure who your tuner is, but Seb (SpecialtyZ) tweaked my tune for free... first, after moving from Germany back to the States (elevation change) and then again after adding the Z1 velocity stacks to my Admin Tuning intakes (not sure if necessary, but erring on the side of caution just in case).
I'd check with whoever your tuner is and they may do the same... then again, Seb is the man so maybe not.
