Problem with Revo remap. ( Random power loss )

[jdjd]

I noticed this the other day and just now it was even worse.
 Under full acceleration my car occasionally loses power at the top of 3rd gear and also when i change into 4th. It happened once the otherday and now again tonight but tonight it lost power for a more prolonged period.  My car is fitted with revo stage 1 software on a switch. I never had a problem with this before the remap. Car has been run exclusively on vpower or Tesco 99

I was thinking it could be a couple of things induced by the remap.
 
1) Overboost for some reason or another.
2) Turbo overheating
3) Possibly some fuel management issue
4) Low fuel my fuel light was just about to come on. literally on the line between the black and red.

Any helpful feedback from any1 with revo or has encounted such a problem would be well nice as its got me worrying if its safe to run it

PS car is otherwise completely standard

Can't say I've had any problems like that. The only power loss I've experienced was when I put 95 RON in instead of 98...

Do you have access to VCDS to log the car to see what's happening?

As a wild guess, stab in the dark as im no expert on these things it sounds like the turbo maybe stalling. Or the dump valve or one of the pipes is leaking and loosing boost (trying to fall off like the 1.8T ones do), Does the car sound the same at standstill if you rev it abit then take your foot off the throttle.

yeah exactly the same. god knows what is causing it, the people carnt take it back till monday to investigate it so im stuck with the lump till monday. Its not everytime its happening most times it accelerates fine across the revrange just on the odd occasion it f**ks up

Can you remove the REVO map and replace it with the exact map VW supplied with the car?
Then you can check if it's just a coincidence and get it fixed by VW.

If you can't then what's the point of the REVO map on cars in warranty?

Isn't this what used to happen on some of the MK5's? And people used to change the diverter valve, to a 'forge' or something? Could be wrong but might be worth a google..

^^^ There was a "miss fire" at high RPM on the late Mk5's which was caused the check engine light to come up on some cars, but this was due to a valve spring fault that was resolved by a VW TSB.

It is possible with the SPS to switch it back to a stock mode, but the code is still resident in the ECU.
