Right people, I've put on a forge 50mm supersize recirc witch is routed back in after the maf, the problem I'm having is when shifting gears in hard boost say 2nd into 3rd the car will bog down and then build boost, the car never done this until I put the recirc on, it ran so much better with out the recirc but I didn't want to stress the turbo so I put it on, what do u guys think? Could it be the recirc is not shutting fast enough? Sent from my iPhone using Tapatalk
