ive got mine wired into the horn button

i throw a switch and the horn stops functioning as a horn and instead sprays nitrous / fuel provided.
1. Its at wot
2. rpm window of 3000 to 6200
3. The system master switch is armed /bottle valve opened (duh)

i also have a relay that throws my stock computer into a mode that reduces wot timing 2 degrees while rhe nitrous is spraying

its a 75 wet nx system on a 1993 corvette 6spd lt1 with a procharger d1-sc pushing 15 psi boost

fuel system is obviously built up and i am using stock ecm still. Works fine with boost (did convert to 2 bar MAP)

engine is still stock bottom end. Holds together fine. But i run e85 and did reduce compreasion to 9.7:1 thru bigger cc afr 195 elim comp port heads

Use a quality parts when selecting your window switch, fuel pressure cutoff switch and wot switch.

If they are Gen 3 Coyotes with 10 speeds, you are going to need a big shot.

Good luck.

those 10 speeds have so many gears they are always shifting all day long

and if they’ve boosted them , that makes them even worse bc they are always blowing off boost with every shift

i agree with Tom - beat them with your driving and dont let them hit you.

they usually crash (i see the youtube and instagram videos) in any kind of performance situation

The A10 is killer. 8-12 millisecond shifts. They spend less time shifting down the entire 1/4 mile than any true manual does in 1 shift.

And when boosted, they don't bleed any significant amount of boost. I have ridden in several out at the meets. The boost will stay pegged.

That thing sounded like it "wasn't shifting"....or it was shifting way too late. Evidenced by the speedo rate almost stopping at the top of each gear.

It was probably more popular mod in 1992/'93.
