I'm running roughly 14psi of boost on a Greddy Turbo kit with TC injectors. My a/f ratio is in the low 11's. I wanted to install an MSD DIS-4 so that I can try to get my a/f up to around 12, and at the same time use the 2 step feature for launch control. Has anyone ever installed a DIS-4 on their box? If so, did you need to use the tach adapters? Also, I have a general idea of the which wires to splice, but would like to clarify with anyone who has done a successful install.

 

im sure you could do it if you know what your doing or your tuner dose.


btw what motor mod's have you done if your running 14psi and have not blown.

 

All I'm running is the Greddy turbo kit with intercooler, TC injectors, Profec E-01 boost controller and an AEM wideband. I also have urethane mounts, a Kaaz LSD and a cutout right before the cat for track use. The tune on the E-manage is still on factory settings due to it being locked. I know it's kinda risky running at 14psi, but it's been doing fine...so far

 

its possible to last with easy accelleration and a light foot, slow build the pressure and don't stay there too long, but only a little longer.. watch that..

Back to your question.. I want to do this to.. except for other reasons, high compression n/a project.. the two step is the funk.. good luck!

 

wow thats risky. you should look into a water/meth kit to keep things cool and safer at that psi setting.
