Joe,
I have never used to additive but it cant hurt to try it as a precaution. A fellow club member here is Az. was having some serious shut down (static) problems last year with his Ultra Lightening and jetcat motor. The fuel additive did not work in his jet because the static was not generated by the fuel flow. We found out it was being caused by a tire slightly rubbing on the strut while the jet was rolling. Anti static spray on the wheels would work fine every time but the final fix was to repair the rubbing tire and run a ground wire to all of the gear and terminate it at the tail pipe where the static was discharged thru a small soild tube. After that was done there were no more shut downs.
Vin...
