1. The unit IS undetectable. The only exception being if an electronic component were to fail and cause something to malfunction. This rule applies to ANY electronics, not just ours. I almost left the part about module malfunction out, but I lay it out like it is. If ANYONES electronics fail, there is the possibility it would leave a fingerprint. I haven't seen a failed unit back yet. Our Test Unit #1 has been running a test program non-stop for going on 8 months now here on my desk.
2. Size???...still don't know what size has to do with it. We could have made it larger and saved some money, but in this case building it with high quality micro-sized Surface-Mount components saves space and allows us to pack a lot of features onto an admittedly small board. We are quite proud of the number of components we were able to put on that board. It's tightly packed. The small size is 100% deliberate. I will gladly debate how size of the unit and the components in it, in this case is a clear advantage.
3. Power Loss/Capacitors/etc... it sounds to me like the user is again speculating as to whats going on. You will pick up a solid 120HP/180 ft lbs on the ford Tune with Painless, which is milder than our tune we sell. I would highly recommend you try it. Painless has put a bulletproof guarantee behind the unit, and we stand behind it as well. I highly encourage you to ask us any questions you feel are left unanswered.

Ok, you need to take a step back here. I will address these three, but the above was my opinion on the unit, which I am free to express. If you, as the person who is going to collect the money when someone buys one, disagree with my comments about the product then so be it.
The ability to be detected:
Techs and other guru's on this board have stated over and over that it is indeed possible to detect a tuner and chip, either electronically or viewing tangible items, like a melted piston. This would include the "Painless" unit, being a product that "Intercepts and reprograms the output".
There is a way to clear the electronic evidence, as stated above, by disconnecting the batteries. You can either wait 10 minutes after that, or touch the terminals together for a few seconds and then re-connect. Touching the terminals together instantly discharges all capacitors connected directly to vehicle power, including the ECM and modules. Doing this would also clear stored values like over boost, and over speed, which are not always stored solely in the ECM.
Again, my opinion at work here. Size is probably not much of an issue, I mean, look at computers and how much they downsized. But a unit that is the size of your palm to control (sorry "intercept and reprogram") your 40-50k truck isn't very appealing. At least in my opinion. When you bunch stuff together like that, you are more prone to MALFUNCTIONS or other problems. Also, if you are worried about not saving money by using expensive parts, why such a cheap display? Surely you could add another 3-4 inches to the unit and make it an LCD screen, to make it a little more user friendly.
What I said about power loss had NOTHING to do with the performance of the vehicle. It has EVERYTHING to do with the electronics of the vehicle, which house the dealer’s first line of defense against people who attempt to add performance enhancing devices. I am sure you get plenty of performance power with this module.
I have a couple questions though.
If a problem does occur, like a blown head gasket, do you warrant the repairs? Probably not, and neither does SCT or EDGE, because then everyone would be out of business.
What is in this “Bullet Proof” Guarantee? How does the unit work if it’s not a downloader, yet claims to be a programmer? (I found this on the web page you listed)
Is it by tricking the computer, or “intercept[ing] and reprogram[ming] the ECM's output”?
Does this unit control the transmission as well, or was that left out of the small unit?
How long has painless been in the diesel world? You know, to see their future problems?
I wasn’t trying to start an argument here. It is clear that you are the seller of this product, and being in that position, you are required to defend its effectiveness and safety. I would like to note however, that since you have only been testing for 8 months according to your post, you are the one speculating on the saftey of the unit.
