Hey guys I tried to do a search for tuners for the 3.0 but they were mostly older threads so I decided to try asking in a new one. First of all will getting a tuner for the 3.0 really make a noticeable difference? If so, What is the best tuner for the 3.0 out there ? those of you that have a tuner for the 3.0 what are your experiences?

 

Honestly, I wished I had saved my money. Its nice to be able to read codes and customize a few of the parameters, but I didnt notice that much of a difference, reguarding power and mpg.

 

Damn really?
What tuner did you use and do you have a 3.0?

 

Go with Fred @ Rogue, his tunes rock.

 

Do the tunes actually make a significant difference compared to stock ? I just want to be sure it's worth it before I drop that kind of money on a mod. What have you noticed after the tune?

 

My buddy just got a Bully Dog for his 2004 F-150 and he loves it. Got 3 settings added power he didnt realize any difference in mpg though.

 

SCT Xcal3

 

Ive got the SCT x cal 2, bought it a few years ago. On a stock engine it may make a difference. I purchased it after I did underdrive pullies and a K&N FIPK system, so its hard to pinpoint. The readings from the butt dyno werent that impressive though. I know opinions are like ********, but Id suggest spending the cash on bolt ons before I bought the X cal. Fyi, Ive got a 3.0, ext cab, 2wd 5 speed.

 

My truck is pretty much stock except for a thrush welded exhaust...always dirty so you recommend doing something like pulleys instead of a programmer?

I've heard about the SCT XCAL3 I'm just pretty much debating now if it'd worth the investment or if I should just spend the money on something else. I'm just curious to know how much of a noticeable there is with these programmers or if its just boloney.

 

what do you all want out of the truck?

the 3.0 isn't very impressive thats what i used to have.

 

^^^hence the 5.0 swap

 

Yep, thats my $0.02. I think the tuner is most beneficial to automatics. On top of the engine tune, Im pretty sure they actually firm the shifts somewhat, don't quote me on that though. Search the forum, but I think best bang for the buck is supposedly roller rockers. When it comes time for head gaskets, thats next if I can find em... Not sure if Fred sells anymore or not.

 

I didn't notice much of a difference after I did the underdrive pulleys. Mpgs wise... maybe 1 mpg, if that... and more a seat of the pants feel than anything.

My next mod would be a tuner to firm up the shifts and get a towing and economy tune. I have a 4.0 tho...

 

yeah wish i had more power in mine too its stock and dang the mpg does guzzle u would think it would be different but not at all a friend who works for napa has the 4.0 says it gets pretty good gas mileage thats strange !
