Since we've entered a pissing match, I have a GSXR that will tear apart any 800rwhp vette and a tuned Eco. My lawn mower, weed whacker, G/F's hair dryer, space heater, outboard motor, kitchen faucet (but not the bathroom), and my recliner are all modified. What's the point of this discussion?

Same question as above, but I tune for gas savings not power. Also the main reason for my tuner was to change the tire size

So here is a question, I assume I already know the answer tho. Is there any tuner company out there that makes claim to their product being undetectable to ford?

If a company would say that I'd but in a heartbeat. I've wanted to tune for a long time but just can't justify the " what if" scenario that runs through my head.

Or for that matter does any have a method of resetting that works?

Well from what I understand with the 5star tunes first thing you do is copy your stock file to the tuner so returning to stock is supposed to reinstall your original tune.

But who knows what's true, in the end it's a risk you take. I'm curious to know if I return to stock then they flash my computer with a tsb update will any future visits show a tune was installed?

Yes it stores stock tune and you can return to stock, I've done it several times with my 5* tunes for emissions testing.

Now from what I understand, Ford will see how many times the system has been cycled since PCM being reflashed, so if you had something happen then you returned to stock tune they could question why there weren't that many cycles on PCM.

I've had mine tuned with 93 tow/performance for two years and have no problems. I do return it to stock when I go in for service because if they flash it under TSB or something else it won't screw it up.

Yeah I returned it to stock but silly me left the tuner in my arm rest. Didn't expect them to go snooping. The mechanic told me next time to leave it at home

I hope it's a GSXR1000! haha

In all honestly, it started by saying people tune for more power. That's not the reason everybody tunes, I would tune because of transmssion tuning is sloppy at best from the factory. It's personal preference really, I'm still up in the air about it, but a friend of mine said that if a tune has been installed, and returned to stock, Ford engineers can indeed dig enough to tell that the PCM has been flashed with non ford software, even if a stock tune is installed.

Now, some tuners correct me if I'm wrong, but the tuner itself actually writes over the stock file from a file stored on the SD card or whatever of the tuner, then when you return to stock, a stock file that is stored on the tuner when you bought it is copied over the tuned file you installed on your truck. Meaning, once you install a tune, your factory installed tune is gone forever. That's why it's key to get a proper tuner that is custom to each specific truck. I know the one I've been talking to provides tunes by specific VIN numbers, and in turn should be the least detectable of all. Now, is that true? Who will ever know, because you know Ford will always say they can detect aftermarket tuners.

Quite honestly, I think it'd still be a tight race. I've been along side my share of FI cars and it's amazing how well they hang in there. I just felt like slinging crap for a bit. I can certainly appreciate an 800rwhp vette.

I originally tuned mine for raw power but I have to say, I rarely use it. The added midrange power and shifting is definitely the best thing about the tune. Turbos come online instantaneously and strong in the low-mid range which I love when I'm running around town and such. The shifting is a lot more confident now, I could never go back to stock. You don't realize how shotty the stock tune is until you have something to compare it to. I really don't think a tuned engine necessarily equates to reduced engine life either. Like I said, I rarely use the power. Sure it's pumping a few more PSI of boost at part throttle, but I rarely wring 10+ psi out of the truck. What would be the difference if I had a stock tune, beating the **** out of it all the time at 14 psi of boost?

I would also like some clarification with regards to the storing of the stock file on the tuning device, specifically the Livernois tuner. When I update the tuner via the internet with a new batch of tunes, like I just did for the 93v10 tune, it started the update by erasing the stock file than adding the stock file. Not quite sure what that means. I was always under the assumption that before a LMS tune is loaded, the stock file is copied to the tuning device for later use.. I'm not so sure anymore.

I think when I got my new tunes online from Livernois that my strategy code was updated from my old stock Jgk3 code to a different 2013 stragedy code. So I'm wondering if I put it back to stock and its not the same strategy code?????

Haha! It's all in good fun! Your driving style and mine sounds about identical. Midrange power would certainly be increased (I know it was on my 6.4L) and that makes the truck fun to drive! I was told by a tuner on the phone that if it copied the stock file first, a download would take nearly an hour or more just due to its shear size. When you update tunes on the tuner, you update the latest and greatest tunes released from ford. This is where it gets tricky, because Ford knows what file was on your truck when it left the factory, and it also knows how many updates they have released. Just like someone mentioned earlier, Ford knows if you come in with the most released ford tune, and you actually haven't been into a dealer to get those tunes (so Ford can track them) it sends automatic bells and whistles to fords data base and they immediately scream warranty voided. This is why again, I'm a little skiddish, because I don't know this to be 100% true. However, each story meshes perfectly from what the tuner told me, and my buddy that works at ford (mechanic mind you, not a salesman).
