Lots of info on this, but much comes down to preference or past bias to some extent.

Yep, there are things the tune can do that the JB4 can't. I love my JB4 but know its limitations. There are things that it provides that the tunes can't as well, so eventually I'd love to do a BMS Back-end flash

Does the JB4 offer anymore power output over the JB1 or is it simply that it allows users to fine tune air/fuel/boost? If I'm not going to use the tuning features of the JB4 will it offer anything for me that the JB1 does not.

It allows more control of fueling so top end is much stronger. Since I went from JB1 to JB4 it's very noticeable.
Edit - JB4 will get you much closer to standard staged tunes where JB1 is more like a stage .5 or .75 lol. I made 289whp/324wtq on a JB1 w/DP in 90° heat

How's you clutch holding up?

Good so far. 11k miles overall and 10k of them on JB1/4. Just don't lug it and don't really boost below 3000-3500rpm. I'm going IS38 on the stock clutch so we'll see how lucky I am hahaha
Hmmm. Boosting below those numbers creates wheel spin with stock power. I usually don't really get on it until about 3000rpm if I'm going to pull on it. What do you mean by lugging it? I never get out of third gear in the city. I'm assuming by don't lug it you mean mashing the pedal on the highway in 5th gear at 2500rpm
Are you currently running a DP or any other bolt ons?
He has the IE intake and IE intercooler with cts turbo inlet pipe and a catless cts dp.

Yep lugging it is exactly that, just downshift if you need more power versus going WOT at low rpm. It sounds like you already know all the good habits
As Mk7gti said, I'm basically full bolt on now. Only thing I don't have is a throttle pipe (running Neuspeed charge pipe post-turbo).
Keep in mind I drive like a grandma 95% of the time, but it sounds like your city driving so a lot of yours will be basic commuting like mine. I go 8 miles on streets to and from work and never hit positive boost. My oil temps barely reach 180 degrees and I don't go WOT before then so not like I have a choice either way haha. People give me nasty looks tho for not accelerating quickly and we all wind up at the same red light

I get the same thing every day. No point in racing from one red light to the next. It's pointless.

My stage 2 ED tune won't boost past 19psi and it only made 250whp on a dyno. Anyone have any idea why?

What are ambient conditions and what type of dyno? It may only boost 19psi if it's cold out since the ECU uses load based tuning. You should be making more than that though.

The ambient temps were in the 30's at the time, but the car does not boost higher than 19 pounds regardless of the outside temps. The tune has a requested boost level set to 19psi, and I'm not sure why?
A 2015 GTI made ~315whp on the same dyno with similar ambient temps with a UM tune.
