Curious why you'd want twin turbo's on such a small engine, with an already small turbo.

Typically, the idea behind twin turbos is needing a large turbo for a large displacement engine, but getting a smaller turbo to do the work at low RPM while the larger one spools up.

This isn't really applicable here, where you can be at full boost before 3500 rpm

That's a multi-stage turbo setup. Usually a twin-turbo involves two identical turbos providing the same boost, usually for separate banks of cylinders. It would be kind of nonsensical to use either setup on any Dart.

So would you recommend just getting a bigger turbo? I need a decent power boost (20-30hp) but I think the easiest way to do that would be upgrading/ adding another turbo.

Easiest way would be getting a bigger turbo and tune. Adding another turbo opens up a whole different can of worms. Hell you might get by with just a tune tbh to get that amount of power

On a 1.4T, the stock turbo can already make more boost than the car will use. The boost is being limited by the OEM tune. A bigger turbo probably won't improve anything, and will just take longer to provide maximum boost. I'm pretty sure a Eurocompulsion Stage 1 tune (which requires no aftermarket upgrades) will make at least 20hp.

Is that something you can do yourself or no? If so where can I get a Tuner for that and how much would it cost?

Always start with a tune. Any tuning shop should be able to tell you where you'll get the most gains.

Plus, more turbos won't do any good without changing the boost controller.

I would actually advise against going with a tune first before doing any other modification. The reason being that each and every time you install a new part or modification, that tune will have to be adjusted to take advantage of the part or modification you installed. Now, luckily with Eurocompulsion, they are the only company that I know of (even with other cars and tuners) that offer lifetime adjustments to their tunes... BUT that is only because you are spending SO much money for their tuner... So, my opinion for gaining power in this platform is to do the basics first and anything that you will want to do in the future... The modern ECU in this car will make its own adjustments to keep the car running correctly until you are done and able to get a tune. That way (and also in the case if you dont go with EC as your tuner of choice) you will not have to go back and forth numerous times paying god only knows how much money in re-tunes every time you put a new part on your car.

So my best advice, let the engine breathe first... Intake and exhuast... then move to the pressure system (intercooler, piping, Forge Atmospheric DV replacement valve)... then move to driver mods and more expensive items (engine mounts, lightweight pulley, short throw shifter, CDV delete if you have a manual and finally things like turbo upgrades, cams) then finally when you are all done with your mods for a while... THEN get your tune.
