Actually uploaded the post on wrong forum, hope some one can help!.

Hi everyone!, I´m having a very weird issue. At wot, car starts fine but when turbo spools low fuel pressure starts dropping, high fuel pressure drops also (can´t say wich one makes the other one to drop), and car starts to have lean conditions and missfiring badly at around 5,800rpms...

Parts already Changed:

Low fuel Pressure Pump
Module that has on top of it.
HPFP Cam Follower was pretty bad so changed for a new one.
New Spark Plugs BKR7
Fuel Filter.

The only code is Low fuel Pressure

Car Specs:
2007 Golf GTI MKV
Autotech HPFP
APR K04 Software
S3 Fuel Injectors
S3 Turbo
Twin Cooler
KN Typhoon
DP
Cutout

Car has being runing perfect for more than 1 year with this mods, the newer mod is the Twincooler but it would be impossible to think hat this can cause that, there was boost leak on the DV but got fixed, a/f got better but still Both fuel Pressures Drop really bad!!

By the way... if someone has the measurements for the HPFP Camshaft Lobe it would be great!

There was a recall for the fuel pressure sensor that's all I can think of since you pretty much replaced the whole fuel system besides sensor
