My 348 doesn't sound right. I hear a turbo whooshing sound from the engine occasionally and it doesn't feel as loud as it used to. It also failed the emissions test I did recently. Had a hub dyno test done a few days ago and compared it to the 2008 dyno test. Power is slightly down and the line at the top end is different. Red/black lines on the graph are from this week. Grey lines are from 2008. Same hub dyno machine. Blown cat or something else? Image Unavailable, Please Login
ahhhh.... looks like I've gazumped the fchat experts Turns out it was the offside Valberton valve on the left side intake of the right intake compartment that caused a warp fart-oni effect in the airbox chamber. Thereby causing a loss of pressure in the cartoni mag chamber that leads into the rear fib fab foni box. All makes sense now
