I see. Well good thing I don't use premium then =) That is very informative and
thanks for it. I'm sure 89 is just fine for the tank and hopefully since the tuner
will be programmed for 89 I'll get that gain from using a higher octane level. I do
want to get some kind of gain especially in passing, acceleration, and a little more
hp. This is the first Ford I've ever owned and I'm impressed. I guess it might be be-
cause of my bike, but I just want a little more response and speed in my truck. Not
that I want my truck to be as quick (pretty sure that's impossible unless I spend an
arm and a leg) but I want there to be more power when I need it I guess you could
say.
