I haven't put an APR tune on my MK7 yet, but the one on my MK5 allowed me to select the stock tune when I wanted to and was fine on 87. Have they taken out that feature?

They haven't been able to make it work. I've bugged them a few times and no word on when it'll be available. That's how i had my mk6 gti (s2) set-up.
Ive been stage1 since 4k (now I'm approaching 18k miles), and the plan back then was to wait for stage2 upgrade when tune switching ability is available so I can do it all at once & not habe to pay another 100 for the upgrade when it becomes available... so yea, still nothing on that. FYI in case yo go w a different tuner.

This is true IF your car is not turbocharged or high compression. If you read the gas label it says min 87 normal 91. In our case the engine is designed to run on gas anywhere from 87 on up. At a certain point more octane won't help because the ecu won't increase boost anymore but for the most part a slight increase in octane will see a SLIGHT increase in performance. It's only a few HP though and in normal daily driving won't be significantly noticeable. If 87 octane makes a huge difference in the way your car runs you should have it looked at.

Many manufacturers now say cars can run on 87. Hyundai has been one of the few of them to actually say that the engine makes more power on premium, but 87 is ok. With today's advanced computers, the ECU will adjust to the fuel. Yes if the car was specifically designed to run on just 87, then premium won't help. Volkswagen does specify that the rated hp was made on premium fuel. They just don't say what the reduced power is on regular like Hyundai had the balls to do. If you feel like your car is fine on 87, then use it. I use 93 and I'm happy with the way it performs. Volkswagen would not make the disclaimer if there was not a difference. Some say the computer won't advance timing, but have you thought about the fact that it retards it when you put in the 87?
So happens I use 93 Shell because my grocery store has a "gas rewards" program with Shell. Shell is also a top tier fuel if the additives make that much difference.

Thats the thing though, im pretty sure at least the 1.8 is designed for premium (correct me if Im wrong)

Nope, it's always been 87. For even more solid proof APR has an 87 octane file for their stage 1 software, showing that it's safe to run 87 even when making 235 chp with our engines.
Also, if you open up your gas cap and check the sticker on the flap it should say 87 (it does on mine).

Yes, but Volkswagen says that the advertised power rating was achieved on premium fuel. It will work on 87, but 93 most likely makes more power

APR did Dyno's of the stock 1.8TSI and with 87 they got 151whp and with 93 they got 175whp. Explain that exactly?
The VW ECU adapts to octane and adjusts itself accordingly to take advantage. This is the case with many other modern turbocharged cars.
I agree that octane doesn't matter on a naturally aspirated car but with so many modern car manfacturers reducing their cars displacements, adding turbos and tuning them to work with 87 Octane the tuning potential is greatly increased since their software is designed to neuter the performance to work with 87 octane BUT can take advantage of higher quality fuel if it detects it.

Read the 2nd page of this thread and this is making my head hurt.
Does someone have to take a picture of their owners manual and gas cap to prove that the North American 1.8TSI VW engines can use 87 Octane?
