Newbie to Tuner, 09 F150 5.4
 

Hello All,

Glad I have found this board.

I have just purchased my EDGE CS and am now debating having it upgraded to Gryphon

I am growing concerned over the runing lean issue, what I have read, the 09-11's have the chance of running leaner.

I have KN 63 CAI, and run Mobil 1, I now have 65518K on my truck.

The main reason I am thinking is for the lean condition, but would really like to have better MPG (currently 17MPG Econ or Tow)(it gets much better W/O cheap gas)

Being a newbie, I have seached a bit, but info is scarce on 09-11 EDGE/GRYPHON.

I really dont understand alot of the technical, so help me out.

I am troubled with possibly damaging my truck.

I was thinking...
Custom 87 tow
Custom 87 Perormance
Custom 93 Performance

Any suggestions?

However, I am running 89 alot, but not faithfully
I drive ALOT, MANY LONG HWY trips approx 12-18hrs
City driving short trips and long idle
A mix of miles from towing also, from an 5x8 utility up to a 29ft camper.
I use my CC ALOT, as much as possible
Average speeds on HWY are 78-84 no load, 68-72 W/Load

How can I benefit?

Thanks in advance
