Car is a 1999 S4
So far i have replaced the Y pipe to throttle body thats new have done the F pipe delete and have done the N249 delete i have presurised the system and it is airtight no leaks present and i keep getting this code
17965/P1557/005463 - Charge Pressure Control: Positive Deviation
The other mods on the car is a full miltec system from turbo back with sports cat's the car has not been remapped so im thinking that maybe due to the exhaust being more free flowing the boost threashold is being over-shot.
Here is the Vag-com log 3rd gear WOT there is a glitch around collum 13/14 not sure what that is about
can anyone shed any light on this or does the vehicle need a remap
Also will it be fine to fit a boost controller to the vehicle and take the N75 out of the equation and set it to the correct boost levil
Thanks for your time
