Has been a great car but needed a new iming chain. I replaced it and now its not getting very much power. what could be the problem? How does it get fixed?

check the new iming chain carefully.
sounds like your timing could be off a tooth check your timing marks
recheck the work previously done
How many miles on it? Was the reason for replacing the timing chain a noise , or performance issue to start with?........AND the other three suggestions!
