Okay guys, I inputed JJ's number, 2709 and 3.55 GR. Alls I have to say is WOW, WOW, and WOW. What a difference inputing the right data makes! lol
It's sooooo freakin close, idk if it's worth messing with it. The mileage was dang near spot on. The MPH was dang near spot on. Here's the breakdown:
55mph truck = 56 mph GPS
15.1 miles in truck = 15 (getting ready to turn 15.1 miles) on GPS
In fact the miles may have been equal, I didn't reset my trip meter (anxious to see MPG improvements and couldn't wait for a full tank to be ran, lol). So the miles were virtually equal, and the speedometer is only off about .5 MPH on the gryphon. I think I can live with that!
But good lord, here I was 2 years later still not seeing a huge improvement with a gryphon vs. no gryphon, but man does this thing have some pep to it's step again! May all be just because the speedometer is virtually right now.
Is it even worth tinkering with again, or is that about as right as it's going to get? Because to me, I can definately live with that and am just impressed with the improvement.
@Shotgun, yeah I was almost empty. I had about 1/8th of a tank when I filled up with the 92 octane. I'm going to run a full tank of it, and then run a full tank of 89 and see mileage differences. If 92 gives a lot better gas mileage, then .20 a gallon isn't too shabby (It'd take 5 gallons to equate $1 and 25 gallons to equate $5....what's $5 if you get 2-3 more MPG).
