The propane kit you are always hyping is super safe since you've never actually sprayed it, nor has anyone else on a SRT10 ram that I have seen (actual dyno and track proven results). Fact is the kit I sell is the only proven SRT10 Ram specific kit, my dyno sheets and track times are posted, and I ran dozens of bottles through it and 50k+ hard miles on a 100% internally stock engine. My kit is nothing super special, but it works very well and looks just as good.
