    Go one range colder on plugs.....under a 150 shot your good to go...I will caution you ....be watchful/aware of your fuel pressure....never "hit it" when your bottle pressure is under 900lbs....other than that....your good man....

    For the WOT switch you'll either have to bend the bracket and install it under the gas pedal or use a TPS switch, like the trigger, as you have a fly by wire throttle body.

    Most guys run NGK TR6s. If you have advanced timing any via a PCM tune you'll want to retard it. The delay timer will delay the nitrous activation. So say you set it for 1 second. The system is armed and you go wot, the N2O won't engage for 1 second. It's to help with traction issues.

    Avoid Platinium Plugs Get The Ngk Tr6 1 Or 2 Degrees Colder Or Iridiums Same Degrees Lower And If You Have A Power Programer Installed Get A Retard Sistem , Dont Use It Above 3000 Rpm And When The Car Its Gonna Shift (you Might Blow The Tranny)

    You'll want to get your car re-tuned after the nitrous. Also if you don't know what has been done in your tune, I wouldn't run the juice until you know weather or not he advanced the timing. Timing advance + nitrous = bad.
