Anyone got a set of APEXi Twin Chamber Blow Off Valves on their TT. Just had a set fitted and I'm now having problems with the car cutting out at junctions. It's OK when the choke is on, however, as soon as it's warm and you dip the clutch approaching a junction to drop a gear, it cuts out.
The car is also running with a Blitz SUS Induction kit, however, this was fitted 4 months ago and has been fine.
Could this be a series 4 problem??
