I have not seen any dyno results, but one guy on the 6thgenaccord website did the JET ecu upgrade on an auto and he said he thought it produced some pretty noticeable gains.
One con I know of: you have to use premium gas after you do the upgrade.
I'll try to find his thread on the 6thgen website to see if I can pick out anything in specific.

In the past I have used JET to upgrade GM cars/trucks. It was a matter of removing one PROM chipand replacing it with another, the results were exemplary. That was many years back but I have heard some unfavorable things about JET since althoughI don't know them to be fact. Pulling the entire ECM to send them for upgrade is a lot of work and hassle, not mention being without a car. Do some serious checking prior to undertaking the task. Pehaps they could supply some customers with the same ride that have had the work done.

Yes pulling the entire ECM is also a con. However, the guy on the 6th gen website said once he mailed it to JET (overnight mail)it was returned to him within a few days (also via overnight mail.) But you do have to go those few days without the use of your car.

the whole JET ecu "upgrade" is debatable, but how they work, from a friend who has one is, you send them a list of your mods and they try to best match the fuel mapping for it. it isnt nearly as exact or precise as a true dyno tune, for obvious reasons. i personally wouldnt waste my time on half-assed-shooting-in-the-dark tuning such as that. i'd be afraid it would mess something up as well as make my gas mileage worse.

It would make sense that the ECU upgrade would be after your turbo, etc...you can deceive, trick, fool the computer into squeezing out additional hp/torque just because it thinks there's more than there really is.
