I would also add that if you're C.80 hours behind in the flying aspects of the course (which, bearing in mind an integrated course normally gives about 160 ish flying hours) that should be more than enough to set monster alarm bells ringing at the FTO. If they're worth their salt, they'll do something about it.
Also - I wouldn't worry too much about the lost earnings you're missing out on by the course taking longer....I graduated in 2008 and there is not even a remote sniff of jobs as yet.....
