Hello
Now and then I see products like this promising increased power, fuel economy etc. What is present opinion of those. Discussed here earlier but difficult to get understanding is it worth doing. I have autobox AR-25.

Dont waste your time or money on eBay Tunning Boxes for the Omega (or any Non Turbo'ed Engine for that matter), they are just MAF Foolers, in its simplest form can be a resistor added inline with the Maf Sensor to change the resistive/inductive Maf Valve into to fooling the ECU that more Air or Cold Air is being fed into the Intake and get the ECU to over Fuel, your just bugger the ECU workings, plus modern systems will detect this with exhaust sensors and attempt to re adjust the ECU fueling back anyway.
On the second part of the post I believe the OP is confusing an ECU Update with a ReMap, an ECU update from the Dealer is simply that, and will not increase Power. An After Market ReMap (or ReChip) is designed to change the ECUs Memory Map for increased Performance, MPG, Power and Torque, although these increased gains on Aspirated Engines are minimal when compared to Turbo Engines.
On the Omega V6's, the early Non DBW, 2.5 and 3.0 had there Map Data stored in an Eprom (Read Only Chip) and therefore the only way to change the Map Data was to replace the Eprom with another Re Programmed Eprom (Re Chip, Chipped, SuperChip etc to name a few), on the later DBW V6's the Map Data was stored by Flashing to the Memory, meaning the Map Data is stored and can be reprogrammed without changing any Chip Hardware (ie known as ReMap, ECU ReFlashing etc). The basic process between the terms ReChip and ReMap is the same, its just a question of how its done, although admittedly there is a vast difference between the early 1980's type Engine ECUs and modern day ECUs.
Ive ReMapped both 3.0, 2.6 and 3.2 Omega's with moderate to reasonable results in Power, Driveabilty and increased MPG, but dont expect it to transform your Car into something it was never meant to be, only noticeable gains can be achieved, if you can add a better free flowing Exaust System with the ReMap then you will see better gains. The 3.2 is probably the one thats most noticeable with a decent ReMap, especially if you can get the Map Data to be rid of all the Tree Hugging elements that are built into the original.
As for your 2.6, a set of G Cams will improve BHP on there own, but add that with a decent Remap and better exhaust system and you will see good gains, Torque wise though its never going to be as good as a 3.2. As for your AR25, without shooting myself in the foot, I personally wouldnt worry, I doubt if your going to achieve the increased Torque which is normally what kills these boxes off, although if your thinking of upgrading to a AR35 that is a worth while upgrade anyway.
