You never need to replace the timing chain if the engin use timing chain(not timing belt).
A back fire is usually the result of an engine timing issue between the cam and the crankshaft. If the mileage is high and it uses a timing chain, you may need to change the chain, gears, cam. IF it uses a timing belt, change the belt.

1999 and newer Chevy trackers don't have a timing belt, they have a timing chain and i was told by my mechanic that it shouldn't need changed at any specific mileage interval.
You are correct that the SL2 uses a timing chain. However, since it uses a timing chain it does not need to be replaced as does the timing BELT. In general, a timing chain should last the life of the engine.
