HYPERTECH pp3 wich fuel?

[Chris Camaro]

ive had it set on the programmer for 93 octane, so what octane am i suposed to run? ive been running 91, this hole thing is confusing

[Chris Camaro]

anyone?

the pp3 comes with a book.

the high octane power tune is intended for high octace fuel.

the low octane power tune is intended for normal octane fuel.

i don't understand your question.

your v6 is tuned from the factory for normal (87) octane fuel.

if you change to the pp3 high octane power tune then use high octane gas.

if you don't have the right kind in your area use the highest octane available when running the pp3 high octane power tune.

ok thanks. i lost the book 2 years ago when i bought it. little brother grabed it, end of story. i just wanted to make sure that running with the high octane settings that i was correct. because someone said that im suposed to run 87 with that setting to get better millege, i think he just didnt know what he was talking about. THANKS GRAYMAN!!!
