Seeking knowledge

[th3_f15t]

Hey guys, me again. I'm starting to think ahead about some engine tweaking for my 2.0T-FSI engine (2007 Golf GTI), but need some advice.

So far I've planned a re-map of my ECU, a K&N panel filter in the stock air intake and a Miltek exhaust. My aim is not to have as much BPH as possible, but more along the lines of smooth and available power. I'd be happy with 240BHP, as long as whenever I want to go, I just plant my foot and it goes.

So now I've fitted the DV+ and a K&N filter, looking at some other bits now. Mainly a PCV valve delete (see page 3 for latest questions and links).

Interesting read that. I noticed that it mentioned about replacing something to the latest version, but I'm confused to what exactly it is that was replaced. Can you point me in the direction of a post (or web page/article) that explains what was the known weak spot?

diverter valve  VW have brought out a new revision Part No: 06H 145 710 D. they are known to fail but forge do 1 for it to

It is a good idea to replace the original DV with the uprated one from VW, its cheap to do and gives you peace of mind.  I remapped mine with superchips bluefin, very easy to do and gave a worthwhile spread of power, good for overtaking.  You will get horrible axle tramp getting away from the lights fast though, that's why VW use 4WD for the fast versions of the GTI. 
Front wheel tyres make a big difference for the traffic light GP.  Poor ones and your wheels will spin, good ones and your wheels go Bang Bang Bang as the front axle bounces up and down.

How much is the Volkswagen part vs. the Forge unit? And is it a job that an amateur mechanic could achieve with a standard socket set and a driveway? I can do full services myself and a few repair jobs but nothing too involved.

If replacing this part means I'll have reliable power of around 240BHP then I'll factor it in before a re-map and new exhaust as it'll be a priority in my mind.

Cheers for that link. Looks straight forward enough to do, but I may just get someone to do it when it's up on the ramps next time. :-)

Apart from this DV, are there any other weak spots in the engine that I should at least be aware of before re-mapping my ECU?

they had a recall on the coil packs too so might be worth seeing if they have been done

Keep an eye on your oil level.  These engines do like to burn oil.
