Help
About 3 weeks ago I went to get my A4 chipped at Hartmann Motorsports. They chipped it but told me the vag-com got codes for:
1. boost pressure control valve open
2. throttle body cannot align
I just replaced my N75(boost pressure control valve) with a new one expecting a huge jump in performance however the car felt the same. Should the ecu be reset? Does it still need the program still need to set in since the valve was broken? Or will the new throttle body make the biggest difference since it can align properly?
Please help
Thanks
