sorry for the pune. I just put a 75 shot[wet 28 fuel 49 n2o] on my lt1. i was wondering if i should get a tune or just get a timing retarder. got a window switch and full throttle switch and i know i should pull at least 3 degrees.
just looking for suggestions.

 

also were is the best place to tap off for the fuel. i tapped of after the regulator. as to not steal from the injectors. the kit shows the fuel coming from the schrader valve which is before the injectors.

 

i ran that same exact setup on my car. I still had the stock tune in my car. and i just tapped into the schrader valve.

 

Get ahold of someone from Pcmforless or madz28 and give them your setup and see what they think.
