lol I know what DSM means yo, I heard from a friend about the brand NOS and I trusted him enough, but if you have proof that it was made by somethin else then hurrah:thumbsup And the NX kit comes with the tps WOT throttle? I know Zex sells a programable TPS switch for users that don't have the nmu, but I don't no jack shit about any other nitrious brand then Zex. I can tell you everything about Zex, but I just say what I hear about other nitrious brands(Like NOS). And I'm on tunners ;) damn turbo guyz think they are the shizznit and they always diss everyone. I will by no mean take offence to anything said though here or anywhere else online, so its all good. So for FUTURE reference, kindly say "don't listen to that guy here'z wuts up and the info to proove it" Not "Man Id bitch slap that guy if he wuz here for speaking like an idiot" If u wanna talk like that, go to tuners, otherwise im learning like everyone else, now I beleive the current Questions is

ZEX Wet or NX wet kit?

And with no supporting evidience I'm going to say Zex just because I feel comfortable using it and like the Zex setup. My 2 cents.....
