I have used it in the past a lot.
Even dynoed engines with it .
No problems even with my O2s. But I was willing to sacrifice a sensor or two if need be.
made over 950hp with spray with no problems.
At 1162 hp I did see some specs on the plug so at that point I stepped up to VP NOS .
All and all it is a good fuel if you can still get it.
Will require a jet change though
