Default NOS Questions on a 99 5.3........

I still have not decided on a radix system or NOS. I dont want to dump over 5 grand on a blower right now. So i would like to know if there is a direct bolt on NOS kit that goes on our trucks. I would like to run at least 100-120 shot of power. Whats the best kit? Will PCM tunning be needed? Will this setup be ok with HPPIII tunning? How safe is NOS, I dont want to blow up my engine. Any additional info would be great. Thanks!

It is as safe as you let it be. Making sure you have enough fuel to keep in from leaning out, making sure you fuel pressure is as needed, not trying to go over the stock limits of the motor. I dont know of a direct bolt on system but a bracket isnt hard to make to mount the system. hppIII will be ok but be careful using 93 tuning. REad up on it if you are unsure. A motor can last a long time if you use it properly. A motor can pop real fast if not used properly
