Looking for support for a custom 207/20X DAVCS setup running USDM Kelfords and e85 on the stock USDM STi ECU. Would like to speak with someone regarding the pnp harness and overall setup.

Email or call anytime with your questions we are here to support.
The Haltech Elite 2500 packages are year/model specific as Subaru had a lot of ECU/wiring variations so please be sure to let us know the exact year/model and market when ordering. (our tuner will also confirm these details for each order to ensure proper fitment.)
