Have you lost performance?
Have you thrown a code?
Could it be just an exhaust leak?
You don't "need" a tune for a decat, you just wont see the performance gains that you "can" get with a decat and tune.
If your front cat has collapsed you can just remove the header and front pipe, punch out the cat in the header to remove the cat honeycomb stuff and the white lagging, inspect and clean the front pipe if required (bits of the front cat), reinstall everything with new gaskets and, abracadabra, fixed for the cost of a few gaskets.
No tuning required.
