HPTuners (narrowband) vs Wideband on the dyno? It's a stalled A4 full bolt-ons/baby heads n cam combo, est. 400rwhp NA. How good of a tune can I get out of HPTuners (done by someone w/ experience) compared to taking it to a shop and pay the bucks for a full wideband dynotune?

pay for the wideband and do it yourself ( or your expert). with time and learning you can make it work great.
dont do the dynotune you will want more than WOT tuning and getting HP yourself will allow you to tune part throttle and all the other things.

I will agree with what's been posted. I paid (twice actually) for tuning on a dyno and all it got me was WOT tuning and idle tuning. Part throttle and street manners still aren't 100% and who wants to go WOT all the time to enjoy their car.
I will be getting one of the tuning softwares with a wideband and learn to tune it myself. There is nothing I find more rewarding than to be able to do something for myself. Whether it's doing my first oil change at 15 or swapping heads and headers at 25 to putting on a 450 sq ft custom deck / patio. I'll be adding custom tuning to that list in the next few weeks.
You can buy a fish and eat today, or buy a fishing pole and learn how to fish and eat for life. The second choice is more expensive up front, and more time consuming, but far more rewarding and will save you money over the long term.

You also need to watch the wideband results you get,
last weekend the car I worked on had its PE table all
jacked by a pro tuner, who also produced a wideband /
dyno plot indicating the car was running a 15:1 AFR at
WOT despite a PE table that should have put it to about
12:1 or less. Probably a tailpipe job. I put things back to
more sensible values using -my- wideband readings (rear
O2 bung). Anyway, maintain a healthy skepticism, I've
seen more than one car now where the wideband chart
is evidently out to lunch, and any tuning on that basis
is just a side trip to the salad bar. Make it earn your trust.
