Still having issues with the ls motor in my hatch I'm getting about 200 miles to a tank and it bogs down at acceleration and has no power whatsoever in any rpm range really.

I'm starting to think its the FPR but I'm not sure. It seems advancing the timing makes it run better but it idles to high and still doesnt run that great and I'm getting horrible gas mileage i haven't even finished my 1st tank. Any ideas?
