Depends...
The guys around here are pretty friggin discriminating - what they tend to demand is typically far and away beyond what most typical homeowner/weekend warrior types would find as acceptable.
That said, "does the chain's cutting characteristics satisfy YOU?" If it does, keep it at recommended spec.
If it's the double-humped tie strap chain, I think you'd have to drop those as well to get much improved bite. That would take considerable effort as compared to just working an hour overtime and buying a better chain.
I, for one, prefer to make something work or at least improve it but I think the general consensus here would be to upgrade the chain and be done with it. I can't say I'd disagree.
