hey, i have an E-Shift IS, and i'm thinking of running NOS on my is. the only mods i have done so far is a AEM intake, and GReddy EVO II exhaust. what kind of set up do you guys recomend? also, i don't want to blow my engine, so, shoudl i get an E management system or what...and if so, what type (brand). i'll probably not use the NOS too often...maybe a couple times every month or two...so, just a little info would be great.
