Only normal issues are with emissions.
Delete with efi live, 50hp tow tune is a perfect tune for anything. A lift pump always helps but not necessary.
When you start trying to get a lot power out of them 100hp+ the cp4 fuel pumps will die fast and completely ruin the whole fuel system.
If you want anything more than a tow tune a cp3 swap is the best thing you could do for it, never have issues again.
