- RZ 350
- pump fuel
This is by far the best Octane boost product I have used. I have finally been able to completely eliminate pinging and engine knock in my 10:1 compression fast road TR6 all the while achieving full power from the setup. PI service was excellent, shipped immediately and arrived next day.
Used Race Gas in my 01 Mustang and car ran great. Can't wait to try it in Corvette in the spring.
It's a good Product and works well , in the applications I use it .
Was able to run 21 lbs boost, perhaps a few more pounds where I was previously limited to 17 psi on straight 94 pump fuel. Stuff works well.
