Hello and Some Chip Questions

[leonard]

Hello TRS
Glad to say I've bought my 2nd Ranger .. kept the 93 3.0 Step side as well
but my new baby *its a tough baby tho !* is a 08 FX-4 Black with lots of goodies.

I've been looking at Chips or tuners for these 4.0's for some time and I've still got some questions that i cant seem to find solid answers too.

one of the biggest draws was being told a tune will improve my gas mileage is this actually true or was i being BS'ed ?

also What tuner /programmer is most recommended. I'm in Canada and will need it shipped so hopefully i can get something that works out of the box properly.
was looking at bama and i think SRT programmers not really sure what the difs are though.

and what kind of gains am i looking at with one of these programmers power wise?

Im in a smaller town to doing dyno tunes are somewhat out of reach for me aswell so im hoping i can get something that just works.

Any recomendations would be apreciated.

going to be buying myself something for my birthday haha.

just basically looking at getting some performance add on without wrenching too hard like i did in previous vehicles also i cant go crazy at risk of voiding warranties on a brand new vehicle that has yet to prove its self .

thanks for replys in advance.

Well Lenard... The engineers at the factory have developed a system that the computer runs that will give you a mixture of horsepower, milage and long life. In order to change ANY ONE of these you will sacrifice one or more of the others.
Your engine gets every possible ounce of power out of every drop of gasoline that it is possible to get.
It would be possible in theory to get more rpm out of the engine by changing the program or causing one or more of the senders to lie to the computer. But the engine depends on changing from a lean mixture to a rich mixture back and forth every second or three to get the maximum economy, and still keep the valves cool enough to NOT burn.
Richening up the mixture would give you possibly more horsepower...but there goes your economy.
Every vehicle that I have driven that had a "chip" added to it drove worse and got worse milage than the same vehicle did when the "chip" was removed in favor of the stock one.
Granted there are guys that have spent the $400 or so bucks that will swear by their chip. This is one old guys opinion.
