Technical Articles

I have written a bunch over the years, below you will find some of the information that I have shared for free with the community. Feel free to read these and share. If you would like a guest writer for your website and need solid technical content please reach out directly for a quote:

Where Do I Find That Table?

See how different, but similar many tuning packages and OEMs are.  Different software packages, but the same functions exist in there somewhere.  It’s really just the layout and locations that differ the most when you are working on the fundamentals of tuning many applications.

Are All Fuel Injectors Created Equal?

Are all “24#/hr injectors” the same?  Definitely not.  Read this article and learn more about why we sweat the details when changing injectors and making sure the calibration tables get the exact data to match them before we even try to start the engine.


Still not sure how I stand on the debate about unknown injectors?  Read this article and get a better idea of just how wrong things can go if you believe the wrong ASSumptions.

Adapting Fuel Injector Data with a Manifold Referenced Fuel Pressure Regulator

With the release of a whole new batch of fuel injector characterization data for some of our clients, we got some questions from the shops and users. The most popular by far were centered around what to do when converting the fuel system to use a good aftermarket regulator. This article gives solid background and easy answers to the calibration fixes required.

Useless Theory and Boring Math

I had a client ask me to review how their latest calibration data for a popular fuel injector compared to someone else’s data for the same injector. I plotted both against the raw data measured on our flow bench to reveal the differences with cold, hard numbers. Data doesn’t care what you think, it just is.

Interesting Things to Investigate over the Winter

Even the pros get stumped sometimes. This time, it’s turbos, boost control, wastegate operation, exhaust backpressure, and a mysterious loss of top end power. Read along as we put a methodical approach to problem solving before blindly throwing money at a problem.

A look at our options for spark delivery and some of the key differences between them. Hosted by our friends over at

Winter Investigations Part 2

In the sequel to our earlier article about boost control on the twin turbo C6, we head to the dyno to find out how theory and the real world collide. We also get some bonus data on ethanol with boost.
