Either way, you really need to work up to the larger shots so you can map your AFR accurately to ensure you don't go stoichiometric at WOT and pop the top of your piston.
To do big shots with relative safety you need to get 2-3 stage colder plugs, pull 4-8 degrees of timing from STOCK, run high octane fuel (highest available), and monitor your A/F ratio very carefully.
You really need to have a look through the nitrous forum on here to get a gauge of what you need to do to run nitrous safely. We don't condone the "spray it 'til you break it" mentality of the former decade.
the kit is from 70 to 150, i def will work my way up. and yes it is wet. i am running the highest octane because i have my baby tuned on the highest octane tune. she def will get all new internals
