Chip the ECM?
Injectors?

Chip (PROM), injectors, ESC, knock sensor.
You could probably bump the fuel pressure up, but it's not the right answer. Without a wideband you'll never know if you are going lean at WOT.

I should clarify, bumping fuel pressure is a band aid for too low rated injectors and tuning. Not ESC/knock obviously. 
You are better off getting a 350 setup so you have those parts, however, if the price is right, my opinion anymore is that you need to either have the original injectors tested, or replace them. I fought with a problem for quite some time that turned out to be weak/failed injectors.

The MAF models take mods more easily than the Speed/Density. It also depends on the specs of your 350.
It's usually best to replace the injectors on the old TPIs anyway since they weren't that hot when they were new and time doesn't help them out either.
I think I have a chip for a 350 system. It's marked ABWN 1606,(check on third gen and similar places to verify that it is for a 350) if it works you can have it. I don't mess with TPI systems much and I don't think I'll ever use it.

Thanks for the replies and offers guys, appreciate it.
I got asked about the scenario on another board by a guy who was looking at getting a 305 TPI for his ride with a 350 and thought it'd be a good idea to double check here, (knowing I'd get the right answers) before giving him any hard info.
Now he can decide for himself knowing full well what he's getting into.
