I'm selling an APR Stage 3 ECU fully loaded.

Has Stock, Pump, Race, & Valet Files

It's a T-Box ECU running on a Hitachi MAF

It's interchangeable with any year B5 S4 that is running on a Hitachi MAF

I'm asking for $250 shipped plus your stock ECU, preferably H, T, M-Box

or $400 shipped for the ECU with no trade

I take cash or paypal (add 4% or send as a gift)

I can work with offers (No lowballers please!)

If you're interested, or have any questions or concerns:

Message me, text me @ 815.980.7004, or e-mail me @ tony2tha@gmail.com
