do i need a tune with a nitrous 75/85 shot, or can i get spark plugs and slap it on their and have fun. oh and where can i get the right spark plugs

 

As far as i know you dont NEED to tune your car.Im running a 75 shot and just posted my own thread asking of alternatives to dyno tuning(and safety) since i just purchased SAFC. But without something like SAFC or some A/F management, i dont think its necesary. Ive already sprayed 5x's before i even put my spark plugs in.In my opinion, with shots like ours just throw the plugs in and enjoy! But like anything, dont abuse...there is always that chance something could go wrong even though chances are slim. ;-)

 

I did need 1 step colder plugs and had to regap them. I kept blowing the spark out.
