What is the difference in mileage before and after tune?Hey it absolutely is worth upgrading the performance. I just put the APR stage 1 tune in my Gen 3 1.8 Jetta and it is a night and day difference over stock. So many more things you can do after that. Good luck!
Hi Adam, Pretty sure we don't even get the is20 according to this post.The 2.0 and 1.8 do not have the same turbo.
The 1.8 has a is20 while the 2.0 has a is38.
If I’m not mistaken that is. Those designations may be wrong. But it isn’t the same turbo. The 2.0 just is a bolt on.

I have a JB4 with Bluetooth for Sale currently if you are still in the market. Used for about 6 months. Yes this engine is definitely worth tuning. Tons of fun to drive when tuned.Hey guys , I own mk6 1.8 ‘TSI I’m wondering is it worth putting the money into to performance upgrades or should I just buy a r32 or golf r ?
