GTS calibrations are developed for vehicles with all factory emissions equipment intact and functional. Features that remove or raise factory speed and rev limits are intended for closed-course use only. These calibrations are not CARB-certified, and the customer is responsible for compliance with all applicable laws, including the emissions and inspection requirements of their jurisdiction.
The GTS difference: a real tune built for your exact car, not one calibration with three names on a dropdown. We’ve got the injectors and turbo kits to back it up, and the in-house support to actually run it. Tuning VW, Audi & Porsche since 2010.
Why we're different ›
A set of four genuine Bosch 550cc (52 lb) injectors for the VW and Audi 1.8T 20v, with USCAR to Jetronic adapters included. Plug and play: the adapters take the factory connectors, so the set goes straight in. Flow is rated at 3 bar.
Who needs them
Stage 3: a K04 or hybrid turbo, with a 3 inch MAF housing and a front mount intercooler. Stage 3 runs Bosch 550cc or 630cc injectors, and this is the smaller of the two. On the AMB (A4 B6, returnless fuel system) Stage 3 takes the same 550cc or 630cc sizes.
Stage 4 big turbo needs 630cc or bigger, so a big turbo build wants the 630cc set or the 1000cc set instead. 415cc and 440cc injectors are no longer supported.
Software
Bigger injectors need a calibration written for them. We build the calibration for your engine code, your turbo, your injectors and your fuel. Ordering a Stage 3 tune? You can add this set in the Injectors option on the tune page, or order it here and pick it as your own injectors. The 1.8T guide covers the hardware for every stage.
Why GTS
Tuning since 2010, as Gonzo Tuning first and as GTS since 2013. Every calibration is written in house and the flashing tool is ours, not a rebadged package, and we never ask for remote access to your computer. Your original calibration is kept, so the car can go back to stock whenever you want it to. Reflashes carry a one-year warranty, and if you are not happy within 30 days you can go back to stock for a refund under our return policy. Support in English and Spanish.
