Many don't change from OEM until they are boosted. If you're running ok, i'd leave it. If you have any worries, grab a set of stockers.

The TR55 is ok for a stock a car with a cam I'd actually have run a TR6...even a full bolt ons stock engine I'd run a TR6...but that said, going to less power than before you won't have an issue if you don't have an issue now.

I run TR6 just fine with my Cam. TR55's are ok for N/A applications too.
