I have a chipped mk5 gti 2.0tfsi that looses power around 3-4000 rpm at full trottle
I can hear the DV flutter a litle bit around 3-4000rpm at WOT, and can feel the powerloss.
Can also hear e litle whistle/whining sound at this rpm.
I have connected the vagcom han checked the requested and actual boost (block 115) Testing in 3 gear
Requested boost: 21,7 psi dropping to 14,9 (3-5500rpm.peak at 3500rpm)
Actual boost: 17,8 psi dropping to 14,9 (3-5500rpm. peak at 3000rpm)
But the requested boost drops from 21,7 psi at 3500 rpm to 15psi at 4200rpm.
Is it normal to drop so fast?
Video:
-My car is chipped, have a full turboback exhaust with a racecat, and a intake.
recently done to my car : OEM Bosh sparkplugs.
Changed Oil.
Changed the DV valve to the OEM "D" valve.
What to do next?
Cange the PCV? N75? map sensor? manual boost controller parallel with the n75?
Pleas help me :) Sorry for the bad english ( i'm from Norway :p)
