I burned the chip myself so I know it is not a position issue. The 100 file seems to fuel heavier at lower rpms resulting in more black smoke. The 120 smoke show lights the turbo so quickly the only smoke you see is gray under WOT pushing 25psi. Guess I was just expecting more as my last truck with similar mods, a DP tuner, zf6 and ABs would really roal some coal.
