Hi all I bought my vrs about 10 month ago from a garage and was told not to remap it because of clutch slip so I didn't bother with it but one day I had a play with my brothers mates Leon fr and left it for dead so we figured it was remapped and also found a egr delete but there was a noise like a boost leak so I took it to a specialist who said its been remapped badly and is pushing the head off the block so now needs a new map and head gasket, has anyone else experienced it?

No one else? Just after advice on best remaps

Wow, lifting the head on a stage 1! Can't recall hearing about it happening even with the hybrid set ups.

Is it monsterously high boost that causes a head to lift? Seems far fetched for a standard turbo if it is!

Someone with far more knowledge will be along soon I'm sure

Not heard a simple remap lifting the head. Too much advance can cause this but not many tuners touch this, defiantly not a none big turbo.

I have no idea I took it to a place called mb Motorsport he's a specialist he said it had been remapped really bad where the boost and torque had just been whacked up and as I was losing lots of water under high boost he said maybe that's what could be causing it so I'm getting the jabbasport map on and the head done if that's what it is

If the garage you bought it from told you it had clutch slip why did you - a: buy it or b: get them to change to clutch??

The other way of finding out how good/bad the map is is to put it on a rolling road. I would imagine you may find spikes in the torque curve.

I've not been to MB Motorsport, but I know the bloke who runs it. So I'm sure Michael will sort the map out. Am I right in saying he hasn't got a rolling road? I would imagine he measured the boost levels in diagnosing the bad map. He could do the same with the new map just to make sure it's OK. Having said that, Jabbasport are a well know remapping firm and are sponsors on here, so it should be right!

No the garage I got it from told me not to remap it because the clutch will give up so I'm guessing the garage never knew it was already mapped the clutch is fine and yes michael only used diagnostics av heard he knows what he's doing as his father has a remapped vrs and it's fine my problems are:

Loss of power revs drop then shoot back up

Loss of water under boost

And a weird whoosh that sounds like a boost leak.

Mb motorsport are saying the head could be lifting but can't be 100% sure as he's never had anything like this before all he says is that the boost and torque is stupidly high

Yeah some remaps simply just up the torque limiter my x percent throughout the rev range. Same with the boost.

Remember a rolling road is a measuring tool. It will not show up bad mapping. Yes it will show you the power curve so any spikes. It won't show how the fueling maps, boost maps, timing maps have been altered. It's very easy to just raise a few maps by x percent and get good power increase. Whether its done well is a different matter.

If you have VCDS log channels 1, 4, 8 and 11. From that I'll be able to tell you some of whats been changed.

I have no idea what vcds is lol all I know is that the garage plugged the laptop in vag com I'm guessing and took it down the road and got the read outs off that

Vcds is the new name for vag-com

Oh right thanks for that
