Have you been having any of the "shifting bugs" people have described here on this forum? If so, did it seem like the tune ironed them out? I know this question was asked a time or two already. Just wondering. I have one little buggy in 3rd gear where it seems like it shifts but doesn't. You can see the rpm's fall back abit, them come back up, and finally shift into 4th. Weird. Seems like its "slipping" so to speak, which I HATE. Wide open is fine. A time or two, I have experienced abrupt downshifts, but that seems to be when it is cold for some reason.

I loaded up the 87 tow/performance tune this morning and took it out for a little drive.
A little early to give an evaluation, but so far when I was out for a drive all you could see was.....
I think my mileage may suffer because of the sudden change in my driving habits.

Yes, MPG will go down. It's hard to stay off the gas pedal when it reacts so well. I put the 87 performance tune on and I think the transmission is done learning. My MPG are starting to get a little better. Not shifting into 6th I think make a big difference, now when you hit the gas you don't have to wait for the truck to downshift then take off. It just goes, and goes fast. I did have 2nd up to 60 mph at about 5800 RPM then took 3rd to 90
, then I got yelled at by my wife we were going to fast.
The throttle response is awesome with these tunes too. I have not tried the economy one yet but will latter, after I'm done having fun with this one.

Another option is SprintBooster if you are only looking for throttle response changes. Plug and play installation.

Don't have or need one on my '04 V10.

I was sitting in the garage waiting for the family to get in the truck to go to the store. So I was playing around with the gas pedal and I was able to rev up the motor to around 5000 rpm's and it sounded great. My son said it sounded like a race car. Now before I got the tune from 5 Star the motor would barley rev at all just sitting in park. Now the sound mainly comes from the intake but the tune make it possible. Thanks Mike.

It's just remapping the go pedal potentiometer position ahead of the pcm instead of a 'tunes' remapping of the throttle response curve inside the pcm.
Little harsh here!
I retired from process control engineering where I programed industrial controls like this all the time. Signals can be conditioned at any point between the operator input (go pedal) and the computer output (throttle position) and you can not tell the difference. The exception here is that the SprintBooster can not get around any throttle limits set by the pcm.
AKA hack job.

It is, and could actually be dangerous.
$295 for what amounts to fooling the PCM to thinking the pedal is in a different position.
Meanwhile, get an SCT X3 from Mike, read codes and do REAL DATALOGGING of Ford OBD-II (not just the vehicle it's VIN locked to) and get custom tunes that you can try out, have Mike modify to your liking, all with a money-back guarantee.
I know, I sound like a salesman, but... come on...

Side note: The Toyota "sudden acceleration" issue that seems to have either been covered-up or wasn't really an electronics issue (which I seriously doubt) had to do with the pedal sensor not doing the right thing. Either the PCM wasn't reading it correctly, or the sensor wasn't sending the right signal in the first place.
Want to play around with that? Really?

So what kind of "footprint" does this device leave on the ECU? What parameters will have been operating out of factory specs that Ford could see if they went digging to deny a warranty claim? I know they're cracking down on tuners on the diesels BIG TIME, just wondering about the 6.2.......
