Big Turbo MPG?

Posted in Blog by admin with No Comments

A popular question that comes up at the shop when people are taking the plunge to big turbo build is “how is this going to affect my cruising mileage?

I just returned from a trip to upstate NY and was able to get a calculated 31.6 mpg through the entire trip.

This is on the Unitronic 830cc mafless file which should be the thirstiest of all the programs…so the 630cc maf file could return even better economy. I shot for a cruising speed of 76mph-right at 3k rpms on the 02M 6-speed. This was carrying 3 people and luggage for most of the trip. According to edmunds, and a bone stock 1.8t Jetta is rated at 31 on the highway.

Other tidbits that could affect mileage

  • 5k miles on bkr8eix
  • Fresh Motul 5w40 and the big oil filter (068115561B)
