Totally forgot about AKS, great shout.

G&A performance over in Brackley know their way around a golf.

Alex is very good... he built half my car :-)

Ah Il watch out for that then!

On my MK2 Leon Cupra R I had the REVO PCV delete kit, Might look into deleting this again.

Yeah just keep an eye out for oil leaks at the bottom of the bell housing and 'under boost' fault codes!

It's mental how much power these engines can make, and how easy it is to extract. It's like VAG are on a mission to rid the world of gasoline with their mental turbo engines at the moment.

Do dont map the new TSI engines.

If your car is still under warranty I'd think twice before getting it remapped.

Google "vw + td1" for lots of info.

The EA888 in the Mk6 / Mk7 appears to make to make far more than rated power. Superchips' before and after mapped dyno graphs for MK7 here http://www.superchips.co.uk/curves/GolfGTIMk7220PS... 266Hp standard...........

330Hp for the stage 2 map .

My Cupra 280 made 305bhp on a hub dyno and 306bhp on a Rolling Road, many other 280's have made 300+ stock.

[SuperchargedVR6]

That just means the either the rolling road is crap, or there's more boost going into the engine than specified. I bet if these engines making more than standard power were taken out and put onto the factory bench test rig, they'd show standard power

VW do typically quote the power on their turbo engines on worst case scenarios though. i.e. on a 50 deg C day in Dubai. Colder climates can typically see as much as 10% more due to the thicker air density.

Another vote for Alex@AKS. He does all the work I can't be bothered to do on my Mk5 R32 and makes it look effortless with everything he does. He's a genuinely nice chap too.

Steer clear of Revo if you can though. My experience of their software is distinctly average.

When my car was in having the original ECU file taken off we compared it to the 300ps Golf R file and guess what... no difference.

Food for thought...Thanks all..

Anyone had a Remus or Miltek exhaust fitted? Thoughts appreciated.

[thebraketester]

Have you looked into BCS systems? Arguably better quality than the others. They are 3" from the turbo flange to just before the tail pip split.

Interesting. 276hp + 258lbft plays 296hp + 280lbft, and the software files are identical? Sure it's exactly the same engine and hardware? Could be turbo sizing. Does the 280 have the same IS38 turbo as the Golf R?

[AJB88]

Yep its all the same, same turbo etc.

[SuperchargedVR6]

That's bizarre then. If there is definitely no torque limiting strategy in the Leon's ECU, it's like buying a 4 finger KitKat and finding you've got 5 fingers!
