loss of power in Evo4! Can anyone help me?

[texten10]

Evo4. I am not a very happy bunny. About 6 weeks ago I had a problem with over boosting, changed the actuator for a forge and changed the dump valve. This cured the problem of over boosting. Now! about a week ago, driving the car hard, coming up to aroundabout, and its like she stalled, coasted round to a stop, and had a look in all the right places nothing. Tried starting the car, but would not idle, on the 3rd try held revs and pulled away gently. Got her home with no problems. But since then there is a lack of power. When driving her hard, when she is at about 80ish, she should be doing about 110-120 but NO. Can anyone help me please.

Your description is as helpful as a bag of spuds in getting to the problem.

Perhaps time to take it to a mechanic who can make some sort of diagnosis.

Perhaps an inlet pipe loose .. loosing boost.

Perhaps you did not connect/seal the dump valve properly..
