You'll want to be familiar with VCDS and data logging if swapping turbos on such a new car. Voltage sweeps, actuator, boost and injection logging etc. Best to be familiar with all aspects of the vehicle when doing these heavier modifications. The older VCDS cables won't work either, the frame rate is very low, you'll need the newer V2 variant. With just a tune on these they go from around ~130-135 -> ~162-167 and ~230 -> 300 on our dyno.

A VNT17 with a front mount and PP520s fully maxed will do 145/285.

I'd run it stock with a tune for awhile and see how you like it, personally find it to be plenty of power.

The OEM bv43a from the 170Bhp CR does comes from factory with a shiny billet compressor wheel however it looses a few blades in turbine side ! This is great for high revs spool however the low revs response suffers badly ! The bv43 turbos are not reliable past 200-220 Bhp and getting a larger compressor just begs for problems ! I always go for larger OEM turbos if possible, I have a bv43a in my seat exeo 2.0 tdi CR...it was 118 Bhp, new gtb2260vklr on tubular manifold awaits fitting !

in ideal world i think we all would mate but often cost is a very limiting factor for a lot of folk like myself who try to make do with best we can get on with what we can afford,or getting devorced lol usually a decant hybid,

not perfect but theyve been doing a decant enough job for years now.. i do agree the bv turbo are ****e , i thought it had a garret

Turbo upgrades don't exist yet, at least not in this market, for the EA288. A turbo upgrade would be complex because of the EGR setup and the air-to water intercooler.

Because of this, most folks who want more power get at tune. Rocketchip wasn't mentioned here, but Jeff has a great tune for the EA288. Projected power is 180HP/300 torque. The big benefits in my opinion are much better accelerator response on tip-in, much more like a tuned rotary pump TDI. And the car pulls much better in 6th at lower highway speeds (60 and up). Fuel economy is largely unchanged, unless you use the power all the time.
IMO the cost/hp is still WAY to high for the EA288 tunes. $650 + DSG $500... $1,100-$1,200 for ~+30bhp then again I'm comparing this to getting LSx motor tuned (auto or manual) where you get a +45whp +40wtq for $380 + headers $200

It's more around 30-35WHP/65-70wtq, and you only have to tune the ECU


There's also slightly more LSx's produced than a single year production EA288.

so you are saying that you don't have to tune the DSG to take advantage the the extra power? looking on your website under "requirements: DSG tune (US and Canadian cars with DSG)" now that's under the 2.0L CR TDI, stage 1 and up.
best i can tell the 2014 DSG and the 2015 DSG are the same... so why does 1 with less hp/tq require a DSG tune and the other does not.

and yet there is not enough of them (or both for that matter)

Can never have enough LSs :P Got a local buddy with a LS3 swapped in his 944, buttery smooth power band.

The software between an ea288 and 189 DSG is fairly different, as is the ECU software. To make the most of it with deletes dsg tuning is needed, but it's not for a normal file. MQB (2015 golf) DQ250s can't even be tuned by alientech at the moment, but we have other tools we've been using to port flash them for the last year or so.

Then don't buy a tune. I've had something like 15 TDIs tuned and have always felt the cost of tuning was well worth it. And it transformed my GSW. It is a manual so I didn't have to have a transmission tune.

well best I can tell 2014 and 2015 gearing is deff not the same, 2K rpms on the 15 DSG is about 75MPH and the TCU software with EPA fix of the 15 was light years ahead of the stock TCU tune of our old 12 CKRA.

Now we did have DMF shudder at 1800 RPMs with stock stage 2, with a modified stage 2 file shudder is 99% gone.

DSG tune isn't needed.
