Tune & Shift Pattern
Here are all the info at one glance. Important is that you select the correct amount of Stage 6 parts you have installed as this will change the tune and also in some cases the shift pattern to use.
Please use the slider below and adjust to the Stage 6 parts you have.

Important! the tunes below are for the maximum amount of fusion parts installed for the selected amount of Stage 6 Upgrades. If you have not all fusion parts installed for your selection, the tune for NOS/OVERBOOST can be different, in this case take the 2nd value (the SEC). The shift pattern is normally not affected.
