Video: Is a tune worth it? We put our GTI on the dyno to find out.

Can you give us a text overview? 

Sorry, I get tired of having to watch videos to get the info. I just want the info, not a bunch of commentary leading up to the info. 

Baseline was X after was Z, here is a dyno chart showing the differences. 

Presumably, 034 Tune is legal,  given you just exposed them to a modification that they are selling.  What are they changing?

This is my boomer trait also.

here's a link to 1:55 where the dyno chart is shown (the rest is dyno discussion)

VW advertised the MK7's torque at 258 lb-ft (273 came with the MK8) so I'm somewhat happy to see you hit that number in the stockish set up.

The 216 hp isn't far off at from the advertised 210 (base model) or 220 hp that came with the performance package.

The results kind of confirm a lot of internet speculation that German manufacturers may often be advertising wheel horsepower.

Thanks for spending the time and resources producing the video.

Yes a tune can produce significant power gains.  Stock tune turbo Ecotec = 260 bhp/260 Tq.  Factory GMPP tune = 290 bhp/340 Tq.  Have to wonder why they didn't standardize the higher tune!

In reply to wspohn :

Possible reasons could be CAFE numbers and/or durability and warranty goals.  And given that "other thread" regarding Cobb tuning, perhaps emissions.

Technically, those are all related to each other.  Emissions durability is a pretty strong requirement.

I'm at the track right now so can't write much, but did want to jump in and say yes, this is a legal tune with an EO number. 

As one who grew up in an era when originally cars didn't even use computers, I still find this tech amazing.  Imagine owning a 1987 Camaro and spending hours installing headers to add 5 or 6 hp, when now you can add a tune and potentially add 50 hp with the freedom to move it back to stock with very little effort.

On a related note, every time I drive a GTI from the last two generations I wonder why i haven't bought one.  When I've been behind the wheel my grin hasn't subsided from start to stop.  If only my wife would be open to a 7th car in the driveway...

Probably the terrible infotainment system.
