I installed my JLT II & XCal II combo about a month ago. Everybody is aware of the power increase & throttle response the JLT/SCT combo gives, so I don't even need to touch that.
But after I installed my 93 Octane "FUEL ECONOMY" tune, I am now averaging 24 mpg! I was only getting 22 mpg on the stock Ford tune and also with the SCT 87 Octane Performance tune. When I filled my tank w/ 93 Octane a few weeks ago, I installed the 93 Octane Performance tune. I didn't notice the mpg increase till I filled my tank a few days ago when I also installed the "FUEL ECONOMY" tune. I didn't think there would REALLY be a difference but there IS!
Does everybody's XCal's come with this many choices, or was this a JLT-added feature? (I bought my combo straight from JLT)
Mine has:
87 Octane (Fuel Economy)
87 Octane (Normal)
91 Octane (Fuel Economy)
91 Octane (Normal)
93 Octane (Fuel Economy)
93 Octane (Normal)
W00T for 2mpg increase and a ton of power!!
