Audi A4 / A5 B8 2.0 TFSI ECU tune

The B8 platform is old enough that most cars have some miles and some parts on them. We calibrate around what's actually there — including known EA888 wear items — and use your logs to make sure the file is right for your car rather than for a fresh one on a dyno.

Audi A4 / A5 B8 2.0 TFSI tuning questions

My car has high miles — should I tune it?

Send logs first. We'd rather tell you about a boost leak or a tired coil before we add load than after.

Do you repair the checksums?

Yes. MED17 checksums are computed and repaired on our own tooling for every file we deliver.

Do you remove emissions equipment?

No. Catalysts, sensors and monitors stay in and working.
