Define what "worth it" means for you.
For NA engines - most of the time there is a little gain. Some power bump, some torque bump.
For Turbo'ed engines - most cases result in quite significant improvement.
From all mods - tune is the best return on the investment, that is say CAI may add 5 HP (about 150-250 USD), exhaust 5-10 HP (500+), intercooler 2-10 HP (300+). Stock tune 20-50 HP (500 USD).
That is for SX version (1.6T).
For NA - tune may bring 10 HP maybe?
They show some graphs, but if I can read it correctly it says Maserati Quattroporte.
So yeah... for engine with 420-520 BHP engine gain of 40 HP is possible (that is less than 10%).
Without good proof (dyno runs - before/after) it is hard to say what results you will get and if any gains are there. And even if they are - say you may get extra 12 HP at 5800 rpm, while between 1600 and 5200 rpm the gains are negligible (2-3 HP)...
I am just theorizing here...
From my perspective of 1.6T - tune was worth every penny. Puts smile each time I press the pedal.
Depends what your plan is.
I assume 2014 SX in Canada is same as in the US. That is 1.6T.
I personally would get the tune for now and see how you like it.
If you can find a reputable tuner, go to them. That would be the best (getting custom tune on the dyno).
Otherwise you are facing CAN tune, as they call it. This means you send your ECU and they program the new maps.
I would not buy those chips that miraculously add power.
For tune you may do K&N air filter drop in (i.e. simply replace OEM) and put racing spark plugs (HKS 40 or 45). Then you will need high octane fuel to get the power.
And new tires more often. And maybe a lawyer to get you out of the trouble for speeding.
This is what I did. Got a spare ECU, put spark plugs, KN, and tune. While up to 60 mph it does not seem much different, I mean - you WILL feel it, it pulls much stronger, but the biggest change is after passing 70 mph. It keeps going strong. I pushed to 100 mph and was unstoppable, comparing to OEM. I did not try further, though. Not really much room here and besides cops might not be so forgiving...
Again, avoid cheap, miracle like solutions.
As for bolts on - sure, they will unlock more power, but at some point you will be close to damaging the engine (internals), so I would be careful.
i will probably do the CAN since no on tnes kias where im at
i have a couple of bolt, and will be getting what you recomend
and by spare ecu do i need to buy another one? and when CAN tuning, do i just send my ecu to the place and they play around with it and send it back ready to go or do i need to get a dyno or have a computer and plug it in after.
the results look amazing i really want that, only thing im a little scared about is that when i get my ecu back that the car wont start or something like that,
