We Be Racing
At its very core, remote tuning is a collaborative effort between the tuner and the driver. We are always honored to be your choice for this role, and will apply all of our experience to help your build achieve its peak form. Developing safe, reliable and high-performing tunes is our reason for existing as a business.
What is included?
This tuning package includes 1 completed revision, which includes up to 10 edits. We begin with a base map as a starting point and work our way through these edits to achieve a polished state. The tune is built around and fine-tuned to one set of hardware and one fuel, subsequent hardware changes may require editing to ensure good function.
This item is the calibration product only.
While remote tuning is the standard of this product, in-person tuning is available in the northern Virginia area.
stock, m54b30 retrofit, Bosch 0 280 218 067 (Audi rs4), HPX, HPX-e, Nissan slot maf in a 72mm ID housing
The standard HPX fitted in an mh-30 housing (as pictured in this listing) is our recommended mass air flow sensor. And though other options do work, we find the HPX to be the most elegant and effective method of metering air for these electronics. While stock MAF is technically supported by this custom product, we can tune for it, but it has very low limits and a build utilizing the stock MAF must fit into the capabilities of its reading capacity. Power goals must match the limits of the meter. For reference, the m54b30 MAF can support up to 340whp.
Top mount? bottom mount? midmount? T3 or t4 or vband? it doesn’t matter, it’s all cool, we don’t discriminate. T2!? Well, that’s a little small, but whatever, let’s do it!
