Hopefully retuning will solve it, but will upgrading my air filter to open-type be recommended?

Short trips lang ako (8kms home-office), in pure city driving (stop-go traffic). Ok pala idling ko with gasoline.
Changing your filter to a cone type would be the same as with your stock filter.

BTW, even if K&N is a washable filter, it still gets more clogged everytime it gets washed. It would still be better to get a new filter to replace the used one. In that light, it would be advisable to stay with the stock filter.

As for your rough idle or even stalling problems, if you haven't changed your filter, try a brand new one. It might be the solution to your problem.
