A Very Satisfied Owner

[WoodWacker]

Hi All

Just thought I'd post my experience with the Gryphon. I'm running a stock 2006 5.4L Lariat that just turned 28Kmi. I added an AirForce1 CAI just after I purchased the truck. I live on theOregon coast so a canopy is a must. It weighs about 400lbs which doesn't help performance or mileage. After receiving my Gryphon and I waiting for the tunes, I logged the 0-60, 1/4mile, mileage, engine temperatures (heads Oil, trans, etc.) and other items over a period of 4 months. Being an engineer this is what I do so I was curious what changes the tunes would make. Wow, first thing I noticed from the 85 performance tune was the crisp shifting; this truck was acting like a manual! Then after 100 miles I went out and did 0-60, 1/4 mile runs. They were 1.5-2 sec faster on the 0-60 and the 1/4 mile runs were at least 2 seconds faster with a much better terminal speed. This depends a lot on how I launch. The thing that gets me is this truck is getting 1.7-2.5 mpg more on my daily commute. I've even gotten it up over 20mpg on a recent trip. I really like the way the engine shuts down when I lift. There is none of that forced air delay you experience with typical automatics. No appreciable increases in the monitored temps on the meters from the base lines. All I can say is I'm a very satisfied customer. Sorry for the long description but I hope this helps those contemplating a purchase.
