AAN Motronic Tuning, 'big turbo' for stock MAF (Volvo K24-7400 / RS2 / Garrett / EFR)

Custom chipset for the 1992-1995 Audi URS4 / URS6 AAN ECU.  Rather than list of all of the turbos we support choose this option for any tune up to 400whp on a stock MAF.  In the order comments let us know your turbo type, fuel type (91, 93, e85), ignition coils (we modify dwell tables for certain coil types), cams, intercooler, injectors, and exhaust.

If you are running more than 400whp choose our speed density option instead.  All of our stock MAF tunes require a 3bar MAP sensor.

We also offer ecu socketing services for $100. Contact us about sending your ECU in.
