I'm looking for an ECU upgrade for my dad's 06 Accord with the K24A8 and automatic. A friend of mine has a Jetta with an ECU upgrade from an Audi/VW performance company. The only thing done to his purely stock car was flash the ECU with significant gains in performance.

APR Audi/VW 2.0TSI ECU Upgrade

Does anything like this exist for Hondas?

 

Just to clarify, my friend with the VW has absolutely no hardware or other physical changes to his factory-stock car. Thanks!
