So, I understand there is no plug-in tuner for the 3.4... I could search that much. but what aftermarket standalone systems work with it well?

Re: tuning 3.4
Yup, I'm running Megasquirt on my turbo engine(still stock engine, just added a turbo and other supporting hardware).
It's really nice to have complete control over fuel and spark. And with a wideband O2 you can get the fuel right where you want it.Wayne<br />94 5 spd Camaro<br />Turbo/Intercooled<br /> <a href=\"http://www.geocities.com/Mustang732/cars.htm\" target=\"_blank\">http://www.geocities.com/Mustang732/cars.htm</a> <br /><br />Megasquirt Stand-alone EFI controling fuel/spark w/ wideband:<br /> <a href=\"http://home.att.net/~basic-4/2ndMegasquirt/NewMegasquirt.html\" target=\"_blank\">http://home.att.net/~basic-4/2ndMegasquirt/NewMegasquirt.html</a>Comment

Re: tuning 3.4
Does MS really offer everything you need to run the engine properly? I wish it had more than a 2 channel batch fire for the injectors...
What about emissions, how have u favoured in emissions testing with the standalone? (provided you live in emission zones)\"Madison\" White \'91 MiataComment

Re: tuning 3.4
My engine runs fine. I get 19mpg right now w/ mixed highway/city driving, mixed boosting/cruising. The mileage rating from GM is 19 city.
I don't live in a county that requires emmissions testing. I passed no problem the last time I took it in. That was w/ the turbo and the megasquirt.
If you tune it with a wideband then there's no reason you couldn't tune it to pass a test provided to still had a cat. But I guess if they plug in the OBD code checker and find out the stock computer is freaking out or not present they may have a problem...
I like this explination of batch vs timed/sequential:

Granted MS isn't setup in the box to do things like EVAP, AIR pump, and EGR, but with coding experience and a little modifying it could probably be done.Wayne<br />94 5 spd Camaro<br />Turbo/Intercooled<br /> <a href=\"http://www.geocities.com/Mustang732/cars.htm\" target=\"_blank\">http://www.geocities.com/Mustang732/cars.htm</a> <br /><br />Megasquirt Stand-alone EFI controling fuel/spark w/ wideband:<br /> <a href=\"http://home.att.net/~basic-4/2ndMegasquirt/NewMegasquirt.html\" target=\"_blank\">http://home.att.net/~basic-4/2ndMegasquirt/NewMegasquirt.html</a>Comment

Re: tuning 3.4
There aren't chips for the 94+ 3.4's becuase they don't have removable chips. They are hardwired on the board but can be reprogrammed.
MSD does make coils for the 3.4:
