Re power loss

[Redeagle]

Of I drive normally it's ok
But still seems to have bit of lag on turbo but if I push down to use turbo it holds for little then loses power and bottom out throttle wise
If I turn key off and on it ok for bit
Can I block off the egr valve? As I believe it to be part of the problem?

What FIAT, Which motor..?
