Supported Hardware for Stage 1+
Injectors must come from a reputable source. Bosch 550cc (0 280 158 117) is our preferred injector, it can be used with E85 and gives you room to upgrade. If you have injectors larger than 550cc, please email us and let us know what you have. We can typically accommodate them, but there is an upcharge depending on size and manufacturer. If you purchase 750cc and larger injectors through Motoza, the upcharge for injectors over 550cc on a Stage 1+ will be waived. Please note that narrowband ECUs are limited to 550cc or smaller injectors.
Bosch 386cc Audi TT injectors or Bosch Green Giant 440s are also options for pump gas. Please see the Injector Policy section below.
If you have a turbo larger than a K03, please see our Hybrid K04 or Big Turbo options.
Intended for the stock MAF, but a 3″ housing with the stock sensor can be supported at this price level.
Diverter valve can be piston style, full recirculating or hybrid, but no BOVs. The Bosch 710N diverter valve is another good choice for Stage 1 and 1+.
No limitations on intercoolers, intakes, exhausts, or fuel pumps. For upgraded intakes, please use a dry filter. If using an oiled filter, regular MAF cleaning will be needed. Any exhaust may be used, but additional track car verification may be required for full support.
Upgraded rods and/or valvetrains are supported, though not at all necessary for stock turbo projects. Cams, upgraded throttle bodies, adjustable fuel pressure regulators, and alternative MAFs are not supported at this price point, but we are happy to quote you if you’ve upgraded them.
Injector Policy
Injectors are the heart of your build. They need to be genuine Bosch or properly modified with a detailed flow report. Injectors must come from a reputable source, there are too many counterfeit and subpar rebuilds that do not flow as advertised, may damage your engine, they waste time and money and we will not support them. This site is, of course, a reputable source, but there are others and we will gladly share that list via email. It even includes other tuning companies; we’d rather you buy genuine injectors from another tuner than purchase cheap, ineffective, or knock-off injectors. Injectors purchased on auction and third party sites that ship in boxes with smiles on them are not worth your money & time. In short, if you are looking for places to save money on your project, injectors are not the place to do it.
We expect that cars will fuel differently based on age and condition, however, all of the injectors supported by the Stage 1+ have a normal range of variance. If your injectors are not within this range you may be required to replace them or flow test them at your expense.
What You’ll Need
A Windows 8, 10, or 11 laptop with a USB-A port. Chrome OS and MacOS are not supported, but software requirements are minimal; if your computer meets the minimum requirements for your version of Windows you’re good to go.
You’ll need an internet connection to download and upload files but not for flashing and logging.
Why Motoza?
More than just an off the shelf file, our logging process allows your tune to be optimized for your car and your modifications. You’ll work with real people who value you and your car. Our tuners can often spot common mechanical issues that prevent you from getting the most out of your build and are happy to assist you as your car progresses. For a decade our commitment to personalized service and the mechanical engineering backgrounds of our staff sets us apart. Whether you’re new to modification or have modded every vehicle you’ve owned, we’re here to support your power goals.
While we do insist on quality injectors and OEM or OE sensors from trusted suppliers, we support most aftermarket parts giving you the flexibility to choose the hardware that’s right for you. Our power numbers represent an average based on third party testing, not ideal conditions on our own dyno. Well maintained cars can outperform estimates. Let’s face it, 15+ year old cars need a little special attention to perform their best and while you may be good to go on the first file you’ll have the peace of mind knowing that our staff is there to ensure that your car is responding well to increased power levels and then further dial it in to ensure maximum performance.
With no additional fees for flashing hardware you’ll have the ability to tune your car from the comfort of home or you can work with one of our trusted dealers but still have support when your car leaves the shop. We offer affordable reworks if you need to add new hardware but are not ready to change stages and additional log reviews can be purchased outside the tuning window if you need diagnostic assistance.
