-8 Speed Transmission Only-
Stage One will eliminate auto upshifts in Manual Mode and will raise shift points in Sport Mode. This allows you to reach the rev limiter defined in your tune so you can take advantage of your entire powerband. Since peak power on this platform usually lands between 6600-7100, this is the most effective and inexpensive way to grab some power left on the table over the stock TCU programming
Stage Two (available now for 3.8 and coming soon for 4.6/5.0) will give you the same features as Stage One as well as increased shift firmness and speed. This will result in faster times at your favorite track or preferred proving grounds
An ECU tune will be required to fully take advantage of the powerband information listed above. Stock ECU programming generally limits your sedan ~6800rpms, while stock TCU programing initiates a gear change between 5700-6400rpms depending on gear and load. If you already have an Alphaspeed tune and aren't sure if your rev limiter was raised, just let us (or any Alphaspeed dealer) know and we'll check
