EGR is not required to make an engine run smoothly; it's an emissions device.
That's not actually true, under the right conditions an EGR can actually increase fuel efficiency because it can reduce drag when you let off on the gas. http://www.tuneruniversity....ts-saving-you-money/

Maybe, but it's another variable to adjust (thus more work when tuning), more plumbing, and you're putting crud through your intake. I have had an EGR delete, and the intake manifold doesn't get dirty like when I had EGR.
The bottom line is that you can have a nice-running engine without it.
Besides, if you're putting a turbo on a car, it seems contradictory to be concerned about whatever minor fuel economy gain you may have due to EGR...

More tuning, no as you don't have to program it to do anything but yes, more plumbing and a dirtier intake. I definitely wouldn't bother adding one if you don't have one but if it's there and you can control it, I'd leave it for future experimentation.

Correct me if I'm wrong, but with a digital EGR (not Fiero vacuum-actuated style), you have an EGR duty cycle table to mess with.
Correct, but my turbo piping would get in the way of the digital egr and the adapter for it. I would either have to move the egr or RE plumb the turbo.
I was wondering if for now, I could get a chip for my Fiero as is. Can anyone do that? I tried to contact Darth Fiero, but I have not received any replies.
Theory is great. Practice is everything. EGR saves you fuel because you can't manage part-throttle well with your foot. In the long run, carbon build-up in your intake and heads reduces performance.
I don't run EGR or PCV into my intake on my race car and there is no carbon buildup on my heads (and intake). See here my engine still in the car with no intake - don't those ports look nice?: https://www.fiero.nl/forum/F.../075502-18.html#p692
The Allante solves part throttle issues with a smaller TB and larger TB in the same unit where the larger one doesn't begin to open until about 1/2 throttle.
People need to stop spreading the performance-enhancing myth(lie actually) of dumping carbon and oil into your entire intake stream. Perhaps if a filter was put in front of the EGR stream prior to going back into your intake, that would be true but it would either get burned or need to be changed often.

Did anyone say that EGR and PCV had no downsides?
Some people choose to use this equipment, because despite the downsides, there are positives. It's up to each driver to evaluate what they prefer.
Myself, on my Fiero, I like PCV, but not EGR.
OP, maybe if you're up to it, you can try tuning it yourself?
I don't see what a long-distance tuner can do that you can't do yourself. The main difference (which may be worth a lot) is experience.

Perfect timing: We got a new IC burner to burn a few chips for my 87 highly modified norm asp 2.8 and we'll also burn a few for my 86 turbo that also has one of our intakes and headers + + when we get them done and dyno tested, we'll likely sell some.
