I purchased my Predator tuner from a local speed shop for $350. Been running it for two weeks. My only other mods are Flowmaster AT axle-backs, a K&N air filter in the stock airbox, and a Hurst short-throw shifter. Here's my thoughts, based on MY expectations when I bought it, which were moderate:


Ease of Use: A+ -- Just plug it in under the driver's side dash and follow the on-screen directions. No batteries for the tuner, it's powered by the car. Make sure you read the prep instructions to make sure you have all the basics ready, like ignition to on, engine off, doors closed, no accessories running. Re-installing the stock tune takes about two minutes.

SOTP Feel: A -- SOTP is very noticable, especially with the 93 octane performance tune. 87 tune feels better. 93 performance tune feels great, and is what I'm using. Throttle response is much improved. I can floor it in 1st now and light up the tires (have a 5-speed), instead of having that delayed, "ramping up" feel with the stock tune.

Customer Service: B- -- Called for a couple of basic questions about possible custom tunes, and the customer service rep had answers but sounded bored as heck and ready to get of the phone. No hold time, at least.

Gas Mileage: A -- Following my usual driving routes, and probably getting on it more because the fun factor is up, I'm averaging 21.3 MPG over the last two weeks. With the stock tune, I was getting 20.2. Too early to tell for certain if it's a true gain, but at least it doesn't seem that I've lost any efficiency. I already had the filter and mufflers on before I bought the Predator. The weather has been quite a bit cooler over the last week here in Tampa Bay.

Reliability: A -- So far, perfect. No apparent rough running at idle, cruising, WOT. No CEL or codes. No backfires, stalling, anything. I ran for 1/2 tank on the 87 performance tune, then switched to the 93 tune. The car took a little longer to turn over on initial startup after I installed each of the tunes, but after that first startup, it's like stock.


Bottom line, if you're looking for a noticable improvement in STOP feel and throttle response, the canned tunes won't disappoint. If you don't mind the extra expense at the pump, definitely go with the 93 tune. As far as how easy it is to get/install custom tunes, I can't speak to that.

alright so this post has made me pretty giddy. But i have to clear up something, you said you can re-load the stock tune? Like if my car messed up (i dunno think of a random occurence) and ford plugged in the diagnostic machine would it show that i had messed with it?(assuming i changed it back to stock before i brought her in)
 
First thing the tuner does is download your VIN (can only tune one vehicle per unit) as well as all of the "stock" settings in your CPU. By stock, I mean it will save as a baseline whatever parameters are in place the FIRST TIME you use the Predator. So if you've had the dealer change settings, or used an XCAL2 to change settings, or whatever the case may be, it's going to save those as your stock tune. If you haven't changed anything from the time you took delivery, the tune you save should actually be the factory settings. It's supposed to give you an error message if your version of the factory tune isn't compatible with your version of the Predator software (can download updates).

The Predator instructions stress that you should only install one of their performance tunes on top of a stock tune. If you used an XCAL2 before, and then install the Predator tunes starting from that point, it can apparently cause serious problems.

Once this is all done, you can install a performance tune. The whole process takes maybe 10 minutes the first time, part of that being your learning curve. After that, you can always switch to a different octane tune, or back to the stock tune, in 3-4 minutes. The instructions say you do NOT have to reinstall the stock tune before you change Predator tunes. For instance, you can go straight from the 87 to the 93.

As long as you have power and your CPU is working, you can reinstall the stock tune.

As to whether the dealership can tell if you've played around, no one seems to know for sure. The most common answer I've seen is that they can see that the CPU was accessed, but not what was done. If a service manager asked me why the CPU was accessed, I'd tell them that I bought a Predator so I could read any error codes that may pop up. If he pressed, I'd kindly tell him that it's my car and none of his business and that he was wasting time that could be spent fixing my car under warranty. ;)
 
woo this is good news! i got one question though about this "one tune thing" So basically whenever i first plug it in its gonna save my stock tune. Cool, i havn't done anything to her so far so its gonna be "stock". So on top of this, i can have one tune i.e: if i filled her up with 93 octane i'd push the 93 octane tune button correct? But further down the road if i filled her up with 87 i'd just bring my predator with me and change it right there? would it un-install so to speak the 93 and then load the 87? Sorry for all the questions but im sure a few more are curious about the same thing :) Thanks a lot man.
 
The tuner comes with three pre-loaded tunes: 87 Octane Performance, 91 Octane Performance, and just plain Performance which is actually the 93 octane tune. I talked to tech support and they recommended getting down to at least 1/4 of a tank before changing octane tunes. When I had 87 octane and the 87 tune, I ran it down to the low fuel warning and filled it with 93 before I went to the Performance tune.

You can also have a couple of custom tunes saved, not sure how many. I don't know if these can be erased or overwritten by new custom tunes.

You can switch your car between your available tunes as many times as you want. According to the instructions, you don't have to restore the stock tune before going to a different octane tune. You can go straight from one to another.
 
Everything I've read says no, that you need a wideband O2 sensor in order to view the AFR correctly. The Ford sensor is narrow band and can only report whether you are running above or below 14.7 AFR, but it can't tell you the actual value. I'm looking at the Innovate Motorsports LM-1 and the XD-16 gauges to try to tune the AFR. Check out the training videos on their website, they are pretty good (also the Two Guys and a Garage segment).
 
I just happened to be reading this thread, and I noticed that someone said that they don't know if the dealer can tell if the computer has been flashed. The answer is yes. I took a Ford program in college about half a year ago and they told us its possible. All that has to be done is get on the WDS, and go to the 'mode 9' data. mode 9 has the computer program code on it, and it changes if there is a tune. the technician jsut has to write it down, and call up a number and ask them if that is the right code. but.... no one on flat rate is going to spend their time doing that. so as long as you dont have a tech that is anal and has some spare time, you will be good to go.
 
Fine tuning a tune?

So let's say I go with the Diablo Predator tuner.... I juice it up to the 93 octane performance 'canned' tune.....
NOW, can I further enhance THIS canned tune to 'my' car by also adding in that I have SLP exhaust and K&N CAI ? For those that know...Thanks for the info :)
 
Info pls? Thanks.

... or is that not a feature....can you not truly 'customize' your tune?
Is your only choice one of the six presets?
 
You can change the basic parameters, ie: gears ,tire size etc. with the unit. A Diablosport CMR dealer can further modify the tunes with special software. You can order them by e-mail or take the car to a local, reputable tuner in your area.

You can modify any or all parameters to your liking. Such as spark advance and/or fuel tables from the tuner itself.
