Don't be afraid of the spray. I don't know what the big deal is if you do it right. On our cars what you need to do to be safe is use NGK TR6 plugs(one step colder), a bigger fuel pump if spraying more than a 100, window switch to prevent any damage due to a missed shift or spraying to early, and excellent fuel. I have sprayed three different mustangs with absolutely no problems because it was done right. I have 4.10's and the giggle gas with no issues except for traction at times due to the massive torque nitrous produces. Definitely work on traction stuff like subframes, control arms, and drs but you probably already know that. I would be more than willing to answer any questions you have about the juice. :happydrunks:
