Default no CEL , but turbo is boosting a bit too much

Ok , thats a lie...got a CEL a couple weeks ago when I stepped on it to get on the Freeway, over boost condition. Cleared the code and have been gentle on the pedal since.
Turbo seems to be kicking on early, really wants to take off, but will choke the engine if I go too hard on the pedal.
Just had the head rebuilt and it was doing this immediately after i picked up the car from the mechanic.
Any insight would be appreciated.

It would be good to know what year, mileage, automatic or stick shift and a little history of your PT Cruiser before you got the trouble code.
Also what engine trouble code came up?

2007 limited, 173,000 miles, code was po234...(I think)...turbo over boost condition.
All sensors are fairly new.

I don't own a turbo, but this might help you look in the right direction.

What exactly is an error code PO234 Set Turbo Overboost Condition
