Does anyone know how to change the speedometer to match 4:10s without installing the tune? on a diablo sport hand held tuner I cant figure how to change the peremeters without installing the tune. I have a 100 shot and was told not to run the tune. How do you just change the speedo?
And can I run the tune with a 100 shot?

 

run the tune......it can only help....richen up a/f ratio too.........

 

The people who I talked to about running my 100 shot reccomended the Diablo Sport Tune. They said it would keep my engine from blowing & make my nitrous more efficient.
