upgrading fuel injectors necessary??? First off, I'm a newb when it comes to the fuel system.
I was wondering if I would need to upgrade the stock injectors to larger ones on my 99 t/a A4. The car currently has all the bolt-ons and was dyno-tuned several years ago, but he never told me anything about how close I was to maxing out the injectors. I will be installing 243 heads and 228/232 TR cam later this week and was wondering if I need to order some injectors before I go get it tuned. I looked at RCeng's fuel injection calculator but wasn't sure what my PSIG is...
Also if I do need injectors, any brand you guys recommend?

Checking the load the fuel injectors are under is necessary to determine if you need to upgrade. Is it likely? Sure. Is it certain? No. Current results with current modifications is needed to answer this. Sorry it's not an affirmative answer.
