1-7 is all that you should look at. 8th and on are OD gears. That's a cool Piece of gear.@Peedystablo82 Look at the Cortex boost controller! It's a VERY advanced controller that can do boost by gear and RPM. You will need to tap your ECM harness for RPM and vehicle speed signals. From there the controller finds a ratio between the two numbers and can determine what gear you're in with no input from the trans.
Now the only caveat, is that it can only support 8 gears. That being said, you wouldn't need boost control in 9th and 10th (overdrive). So it should work. Email their technical support and ask, they are extremely helpful.
