We offer our own line of custom chips to maximize your individual modifications and fuel requirements. At the moment we only offer 8-bit upgrades for the 1990-1994 TT and 1990-1992 NAs. We offer chips, bin files and also socketing services. We recommend you ONLY use trusted fuel injectors! "JECs" or "DWs" do not fit the bill. They are merely drilled out, modified, and or Chinese garbage. We can email you the tune file if you have a Nistune board. If you want a file put (file only) in the mod list and choose "will call" to keep from getting charged for shipping.
If you need socketing services please send your ECU with P.O. receipt to our address listed on the site.
Please call or e-mail us for more information.
