The cars are so complex now that it can be any number of components that causes an issue, especially if that software is running perfectly on other cars.  Over the years I've had boost leaks, MAF issues, coilpacks and even a split intercooler that have caused problems, but initially everyone looks to the software.  It's only when you can do thorough diagnostics that you can see (hopefully!!) where issue is.  A session on a dyno with a good technician may save you lashing out 500 notes on a different remap only to have the same issue just wearing a different badge.

vRS Carl:
Just as a bit of background I have replaced the following

MAF sensor
MAP sensor
Turbo outlet pipe
Turbo intercooler pipe
BSH Catch Can
Relocated DV and replaced DV
Lamda sensors checked all fine
Throttle body intake pipe replaced
All coil packs replaced
Cylinder Head Cover and Gasket replaced
All other hoses eyc in the engine have been replaced with new oem ones

I have spent near £900 so far trying to locate this hardware problem.

Everything on the car is 100% working as should. Keith at JKM has spent hours looking into this problem and can't find a hardware related problem. I have personally stripped down checked, cleaned, Re-Checked and finally checked again before replacing everything on the pressure side of the system.

The logs for the for the car on the road were completely different to on the RR. It's just now the Logs on the road are manifesting the same as on the RR. The car is going back on JKM's rollers next week and if I still have a loss in power then there is only the software that is left.

Unless anyone can think of anything left for me to check.

I'm not slagging REVO off and everything was fine and perfect on the car at Stage 2. It was when I went stage 2+ that the problems started. I have as already said tried tested and in some places replaced everything that could be a problem.

To be fair Kev Hall was quite helpful with the emails and logs I sent him.

This is just my personal opinion but if I were in charge of REVO I would go out of my way to prove to a customer that the problem was not software related. Not , depending on who you speak to, instantly blame the car/hardware.

REVO is very very good. But they are not flawless as they think. No software ever is. 

Just to also give some perspective as to why I'm 99.9999% certain it's the software. I know of another Octavia vRS (who has since gone K04) that had the same Stage 2+ file. His car went on JKMs RR and his dyno graph was IDENTICAL to mine. It had the same problem in the same area. The power and torque where also IDENTICAL. The only different hardware on his car to mine was he had a 3" turbo downpipe whereas I have a 2.75" Miltek Turbo downpipe. He has a Forge Twintercooler I have an S3 intercooler otherwise everything else is the same

Now you could put that down to a freak co-incidence. However when a mate who has a K03 Leon FR and he got the exact same as me and the other octavia. Identical dyno graphs identical area for the problem

That to me suggests software. What are the chances of 3 cars all at the same state of tune ( different mods in terms if makers bit still all the same )

I also know that the REVO K03 stage 2+ file is different to when it was first released. I'm talking the official release aswell not a BETA code.

Anyway thanks for all the input guys. Keep it coming. I'm always willing to listen to advice and others opinions.

Reuben at Tuningwerkes in Croydon has been running the APR Stage 2 + equivalent for a while now on his KO3 GTI. May be worth phoning him and asking a few questions? If you're local I'm sure he'll take you out in it too!

ukdub on here is also running stage 2+ on his k03 car...

i looked into APR a bit before changing from bluefin. but i could not find any dyno proof of APR at stage 2 or 2+ apart frpm on america where they all manage at least 500 wheel horsepower at stage 1.  i did like the idea of switching between maps on the cruise control stick though.

i was so certain of going revo, but carls stage 2+ issues were a bit of a put off and the fact harrys car did the same as well made melook into others.  then i saw how well bens car performed at stage 2 in comparison and how much cheaper it was so i thought id guinea pig my self for that one.  there are alot of guys on briskoda now with his software singing its praises.  he must be one of the predominent tuners on there now.
