Title: Map in the new year - what to do before?
Post by: RichardFellows on December 17, 2014, 09:00:46 pm: Hi guys,

I'm looking to get my 07 GTI stage 1 mapped in the new year, either by my local Vag specialist or my nearest Revo dealer. At the moment the car is stock but before the map I am planning to do the following:

1. Subtle powerflow backbox
2. K&N or uprated panel filter
3. D+ Diverter valve
4. Minor service

Are there any other mods that would be worthwhile or should be done be done before the map?

Cheers!

As said above - PRE CAT DELETE!! http://www.mk5golfgti.co.uk/forum/index.php?topic=41083.0

Also get a Rev G DV (it holds boost better than a D)

Check PCV is good, and if you haven't replaced it - CAM FOLLOWER :happy2:

I'm still trying to keep the MPG fairly reasonable so I don't want to do anything too drastic to the exhaust system, but I have previously looked in to a pre cat delete.

Where's the best place to buy an upgraded DV, other than eBay?

remove pre cat
latest DV
maybe a HPFP rather than cat back, you will get better mid range with a HPFP. Cat back is more for sound.
Panel filter
