How much tuning can be done on factory pcm? ^ Like the title says. I was curious about things such as; can you have the fans programmed to turn on at an earlier time to match a lower thermostat, or can you delete the egr and o2 sensor codes from the stock comp? Things like that. If this has been asked and exhausted I apologize (please post a link with the discussion), guess I didn't use the search carefully enough 
Also if i'm on the right track what else could you do with it before having to upgrade? Thanks for the help

It all depends on the program. Everything that you stated above can all be done with a basic handheld programmer. Once you get into programs such as EFILive and HP Tuners, there's A LOT more tables and things to edit. Here's a list of just the "Engine Calibration" folders available in EFILive. Most of these folders open into sub-folders which then have multiple tables.
Fuel
Air Pump
Barometer
Cat Converter
Purge Canister
Abuse Management
EGR
Engine Protection
Rev Limiter
Idle
MAF
Shift Light
Spark
Torque Limiting
Traction Control
Then there's "Engine Diagnostics, Transmission Calibration, Transmission Diagnostics, Fuel System, System, and Speedometer". Add the ability to run Custom Operating Systems (COS) and you will have way more then you know what to do with.

I don't know how it slipped my mind before, but you can download the EFILive software for free. It will run in demo mode with no license. Click on the link below and check out the software for yourself.

550 at the rear wheels with a stock pcm,my tuner told me in order to go to the next level I would need a stand alone system.But the stock pcm could make
more power with additional mods,however the stand alone would make
fine tuning easier & make more power than stock.My cam is huge but the stock pcm,in my opinion is fine-after some finetuning it runs as smooth as
a stocker.Alot can be done with a stock pcm,in the hands of the right tuner.

Thats awesome! Thanks everyone for the education! Ya I've been told about EFI Live with Roadrunner, but thats about an 1100 dollar mix. Pretty expensive for a car that I won't have my afr/comp (thats another 3grand) on for a couple of years, seeing as how i'll be working on an induction system/suspension/9'' ect ect. Well thats great to hear I had no idea of the capabilities of a stock pcm. I really appreciate it everyone, really can't thank you enough!!

Shoot I forgot to ask, say I wanted to do an sd tune without the maf sensor, could an sd tune be performed on the stock pcm also?
O and thanks SHALLOW BAY for that link, way to go the extra mile LoL
I'll be checking that out too.
