    Not sure those injectors are going to keep up with the juice.

    I am building a very similar 402. I am running a 248/254 629/622 113. TSP grind.

    Get a custom grind, usually cost the same as an off the shelf version and can get more power made specifically for your application

    I was thinking the same on a custom grind. Also on the injects, they should be fine. I`m running a dual nozzle TNT wet kit. Thanks, guys!
