Hi folks,
Just fitted a decat to my Stage 1 MK5 and all went well, however it now idles at nearly 1,500 when it’s up to temp, which is a pain in traffic as well as just leaving the car running. The car has had a PCV Delete, it’s also got GFB DV and ram air induction kit with Scorpion Cat Back already fitted as well as being mapped.
Any ideas?!
Cheers
