Hi
I'm going to install window switch on nitrous system in mx-3 klze .
Was wondering what is the highest RPM i can have the nitrous on??
The red line is at 7000 RPM
i would set them at like 6,800
is it safe for 2 gear if i will hit red line accidentally on 50 or 75 shot??
What do i need for 75 shot??
do i need piggy back chip??
i have 1 step colder plugs,FPR sard
thinking about setting up the fuel pressure on 60 PSI while spraying 75 and check it on wideband O2 sensor
Is it the NOS SNIPER system good for 75 shot??

you could possible upgrade fuel pump.. i no for liek a 50 shot u dont need too ..
spraying till 6800 is good too..

If you're running a wetkit there is no need to put the fuelpressure on 60psi

I'm driving it with a 50shot with 40psi and it's still great

you guys got any info on installing a msd controler to retard timing. this isn't chevy hei(I'm confused) since your running nitrous already did you do anything about timing or has your engine taken the abuse pretty well.
