I am looking at buying one but have an issue with it for the time being. On the GMS website, they say that you have to run Premium gasoline with the Predator tuning. This gets kinda expensive so I want to know if you can run regular and adjust the timing or is there a custom program you can get for running with lower grade fuel. I know the power output won't be as high, but I can live with that until I get a cam and have to run premium.

 

james from www.runninwiththedevil.com can make you a program for use with regular octane

 

Personally, I would get a custom tune and be done with it. Not knoocking the Predator. Its a great hand held. But your stuck with it for life. Plus there is NOTHING like a custom tune! IMO.

 

the hpp3 does premium and regular tuning...

 

i run 89 with the stock predator tune and no problems.
