The only cars over in Greece that we've seen have issues and then be okay with other software are those that have had factory update hardware and software between having Revo and going elsewhere. Our dealer TSB states to not touch a 1.4tsi that is showing any of the problematic symptoms. And there are three performance modes built into the software to allow running in different conditions.
There's a difference between peak power and power under the curve. A lot of time was spent going through data on Carl's VRS, but unfortunately we've never had the car in our workshop. We do know that the stage2+ software on a 100% healthy car does make more power than stage2, which is specifically tuned to work within the limitations of the stock high pressure fuel pump.
The only issues with CEL's on ED30's is something we've seen recently, all of those cars affected were rectified within a couple of weeks and all of those owners are running trouble free and have been looked after for their troubles.
As you say the 1.4TSI issues are difficult, there are known issues with these engines. We have a very recent warranty form forwarded to us from a main dealer for a completely standard delivery mileage 1.4tsi that needed piston rings replacing... had that not been caught that would have been yet another stock car needing a short engine.
Revo software gives the ability to be the top performer, with the built in adjustability it also allows dealers and users to set the car up in a very mild state of tune.
Revo state a seen power/torque gain, and give the seen stock figures not an exaggeration. A lot of flywheel dynos give 'high' readings in performance mode, they also do in stock. Giving both figures lets everybody see the performance gain. We'd love to quote power at the wheels but there are too many people that don't understand those figures. Peak figures are larger irrelevant it's all about the power/torque under the curve. We tune for drivability rather than numbers.
Revo software is only great software if its setup well on an 100% healthy car, due to the nature of our software and dealer network there are a lot of users out there so you tend to hear a lot more about Revo experiences than other software. The adjustability gives a lot of flexibility to cater for different needs.
The 'it’s a boost leak' is a joke, but that all comes down to the old issues with diaphragm type DV's on 1.8t's that used to fail left right and centre. When you deal with the same engine type, you see the same failings. Checking the DV for a boost leak is and was a very easy thing to do that didn't cost any money, therefore on the old 1.8T engines it's always the first thing to look it in regards to a loss of power.
Revo software is sold through a dealer network, that being the case customer service from Revo tends to be through a third party. Customer service is the top priority, but it's not always easy to keep everyone happy when most of the time someone else is dealing with the end user.
There is a lot of choice on the market, and 90% of the time anything that's chosen is going to drive better than a standard car. As you can see people will side with the company they've spent money with. There's some good software out there, but there's also some really bad stuff... luckily the companies that tend to resell un-branded software that has minimal development don't last very long. Speak to some of the big name shops out there; Awesome, JKM, AMD, etc, etc. there's a reason they're all using Revo.
