Has anyone experienced what feels like the throttle being shut down. The power starts to come on hard, then just flatlines. Traction control isn't on. The torque management has been turned off, The dyno print out just flatlines, The car's not making any where near the power it should be. Any ideas/suggestions?

Trade it in!

On a more serious note it could be valve springs if its making power then going flat. What rpm does it happen at, have you got a dyno graph you could post up.

Nah it's not the springs, it's got crow valve springs in it. But thanks anyway mate. Haven't got a dyno print out I can put up at the moment :-(

Plugs/coil pack may be rooted... Not producing enough spark...

Or maybe a fuel problem... Cleaned filter lately?

It's brand new filter, brand new S and F intank pump. Brand new bosch 044 with plazma man 2 litre surge tank. Brand new weapon X coils. I rekon there's some hidden torque management issue still there, Even though it's been turned off, It's had throttle issues before. Like a really arresive surge, But that got tuned out of it. Just this issue now. Thanks for the suggestions though, keep them coming
