dazevo

Just took delivery of my new motor lasy thurs and i,m happy to be back in a scoob (owned a evo 6 last 12 months)very impressed with the sti 7 fitted with ppp thought it was slower than the evo at first but now i,m getting used to the 6 speed box i personaly think its quicker than the evo. anyway when i boot it hard in 1st 2nd 3rd then when in 4th at about 5k revs it starts hesitating up to 5th and the same thing happens hesitating and loss in power no probs lower down the bow only 4th upwards took it back to the dealer and they seem to think its the maf sensor supose to be getting a new one tomorrow anybody else had this prob or is it a bit of aone off DAZ........
