im having to run race gas now on my nitrous tune, ive heard that torco can do the job but im not sure if this is the best and safest way. but for those that are running race gas were are u getting the gas. i know that some have race gas at the local gas stations but im not that lucky here. i no of a website that my tuner uses but its only sold in 55 gallon barrows and u have to buy 2 b4 they will ship it.
