Ok so I have a 2005 vw jetta 1.8 GLI. There is an apr intake and a tune on it. Every thing els is stock and im looking to make more power with a small budget. If I could get some advised that would be great thank you.
Get a better tune/software. There are more aggressive ones out there. Upgrade the exhaust from the turbo back. There really isnt a whole lot of major power adders after the tune. That's the best bang for the buck. Post up in the mk4 section. More people will chime in that way.
My bad. I thought I saw Apr. Revo is pretty good. You could upgrade the intercooler, charge pipes, turbo inlet pipes. You will notice a little difference in power but not much. Usually just makes the car pull smoother.
