Advantages of having a gryphon php?

[ticopowell]

Just to add on to Jack's posts, I also noticed a distinct upgrade to the power during passing. Also the quickness of the shifts on top of the extra hp makes me hate going back to stock!
I have an 05 XLT with the 5.4 just for reference.
Also the 89 octane, if the engine isn't tuned for it, really can't provide more oomph. It also won't help in gas mileage for the same reasons as power.
How it works is that the octane makes it burn slower under the same pressure, or burn at the same rate under higher pressure. This is an advantage in high compression motors, such as your motorcycle, or most racing engines, but in our trucks it isnt necessary, and they can't take advantage of it without tuning. With some octanes, I dont think 89 is far enough off of what our trucks are designed for, it can actually hurt gas mileage and power because it burns too slow. this could possibly leave unburned gas in the cylinder which would then exit out the exhaust and possibly causing backfires or in racing motors that cool blue fire .
Hope I helped you and everyone understand more , and if I am wrong, feel free to correct me!

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.

Better drivablity and the seat of your pants dyno agrees too.....

Sounds good. I'm very excited about the programmer and the new tunes.
