Well I am thinkning of stacking a something with my Quadzilla box what do you guys/gals recommend? From what I've read the obvious would be a Smarty but what would be your 2nd pick? Also if i was to buy Edge Jammer nozzles is there anything that needs done other than screwing them on is there? Do they need shims or anything special be fore installing?
Thanks for the help!

 

For the nozzles I would recommend getting the injectors pop tested after assembly.

yeah pop test the injectors to match. alot of the rough running that is complained about is due to not testing. with the stack TST and smarty
