At Haag Performance we offer full dyno tuning service to all our Spec Miata and other engine customers, as well as to anyone who needs it, regardless of the engine builder…..and dyno tuning is possibly the least money that you will spend to get the best return on your racing dollar! The HP gained per dollar spent is normally higher than any other work you can do on your car.

The portable DynoJet rolling chassis dynamometer that we use is the industry standard in dyno’s and provides accurate real time measurement of the engine output and a host of variables that we use to tune your engine to maximum output. It has a full weather station so that we can tune specifically for the current weather conditions or remove the weather conditions from the equation and give you results that will work at any track.

While some cars arrive at our dyno very close to optimum tune, it is not uncommon to find Spec Miata motors where just a few pulls on the dyno and a small amount of tuning will yield gains of more than 10HP and 10ftlbs of Torque.  Gains like this on cars with only 120HP are significant and make the difference from running near the front or running mid pack.

While the car is on the dyno we are able to observe, set and optimize many parameters that affect engine performance:

  • Base ignition timing
  • ECU timing and control
  • Sensor checking (crankshaft, camshaft, O2, IAT)
  • Coil output
  • Air Fuel ratio adjustment
  • Fuel injector delivery and pulse length

Remember that dyno tuning is both an art and a science. The data and science provided by the dyno computer is just the start. This information gives us black and white information that forms the basis of what we do next, and that is the art. A highly skilled and intuitive dyno tuner, in order to get the most of that engine, needs to add to the data a range of parameters that include the track it will be racing at, and where the power and torque need to be in the RPM range for that track (tuning for peak HP and TQ often yield a less than optimum result) the skill level and aggressiveness of the driver driving it, the nature of the competition in the field that it will be racing in drivers request regarding where he wants to be on the performance vs. durability graph. Additionally, we are also able to do negative pulls and check your rolling resistance that will highlight areas for future work in terms of transmission, differential, wheel bearings, brake caliper drag and more:

  • Calibrate on car AF ratio sensors to dyno data
  • Do track specific tunes
  • High HP for tracks with long 5th gear straights
  • High TQ for tracks with elevation changes or where grunt is needed out of corner

Please call, text or Facebook Mike Haag to schedule tuning.

Haag Performance recently caught up with Andrew Holifield, who won 1st Place ITA at the Spec Miata Festival Sonoma Raceway 7/2/17 . When asked about his love of racing and how it all started he had this to say:

“My love for racing started as a kid playing racing video games with my free time. As I got older the racing games got more and more realistic and eventually in 2006 I went to my first high performance driving event. The track day was run by Hooked on Driving, I drove Thunderhill in my street car, and it was a blast! I was hooked.

In 2007 my Dad decided to go to SCCA driver’s school to see what it was like. My brother and I crewed for him later that year at several races. The following year, 2008, my brother and I went to SCCA driver’s school ourselves and we’ve all been racing ever since! We’ve been sharing a Spec Miata (sometimes two) between the 3 of us drivers. On a given weekend whoever isn’t driving is typically crewing to help keep the car running or being on radios during the race.


I enjoy sprint racing several times a year as well as coaching with various track day groups. I try to drive Thunderhill, Laguna Seca, and Sonoma Raceway each at least once a year. In 2015,  I participated in the 25 Hours of Thunderhill for the first time as a driver and then again in 2016. My dad, brother, and I are currently building an NB SWpec Miata that we hope to have on track soon and are looking forward to many more years of racing!”

We are looking forward to seeing the new NB Spec Miata out on the track soon.  Keep up the good work Andrew!

Tupper Hull has campaigned his 1990 Spec Miata since 2005 and was the SCCA ITA Regional Champion in 2015 and 2016.  He placed second in the Spec Miata Toyo (SMT) championship in 2016.  Tupper was a mid-pack racer until he connected with Mike Haag and Haag Performance.  He not only benefited from the professional engineering provided by Mike, he was helped tremendously by the guidance and coaching Mike provided to help him become a better, faster driver.  Tupper currently shares shop space with Haag Performance Sacramento and helps out at the shop when he can.

We look forward to seeing Tupper out on the track!

Tupper at NasaNorcal Sonoma Raceway June 18, 2017 with grandson

Congratulations to Nick Sommers, a young driver brand new to SCCA and SFR. The SFR Double Regional 1-2 AV8 Super Cars was his first-ever SCCA race. Nick came to SFR from other venues, including karting and NASA. The high school senior has been road racing since he was 14, the age when NASA allowed him to run. Due to track age limitations at the time, Thunderhill is the main track on which Nick has raced.

Nick and his father, Greg, who had to sign a Minor Waiver to allow Nick to race, had some difficulties in maneuvering the SCCA licensing process and were referred to Gary Meeker, NorPac Driver License Administrator. According to Dad, it was amazing how Meeker cut through the red tape and got Nick his license PDQ, based on his prior experience.

Nick rewarded his Dad and Meeker by doing them proud at Thunderhill. He took the pole position for both races and won both races in No.83 SMT 1993 Mazda Miata. And this was the largest group – 36 cars on the track out of 41 entries.

Sommers won overall and first in Class in Group Seven both days. Both days he qualified ahead of his friend and fellow high school senior, two year veteran in Mazdas, Tommy McCarthy in No.23 SM 2001 Mazda Miata, who gridded first in SM.

Nick explained that SMTs are Miata’s running on Toyo Tires, and SMs are Miata’s running on Hoosier Tires. Sommers said the Toyo’s are harder tires than the Hoosiers.

In Race One Sommers led from flag to flag and turned the fastest race lap of 2:08.487/80.301 mph. His Margin of Victory was 15.340 seconds, ahead of Tim Auger in No.07 SM 1994 Mazda Miata. Alas, McCarthy pitted while leading SM, with a differential problem.

Sommers was one of those helping McCarthy get ready for Race Two. Again they gridded 1-2, and had a good battle, nose to tail. McCarthy got by for two laps, but Sommers recovered to take the photo-finish victory.

Congratulations, Nick and Greg!

Haag Performance thanks you for your continued support!

Justin Casey, winner of  the 2016 NASA Northern California Championship, had this to say in a recent email to Mike:

” 2016 was a very long and challenging year. With persistent efforts between Mike Haag and I, we were able to develop a consistently reliable and powerful car.

As a result of our combined efforts, I was able to clinch the 2016 NASA Northern California regional championship for Spec Miata and I am very grateful for that.”

We are so proud of Justin for winning the 2016 NASA Northern California Championship!! Congratulations on a job well done Justin!

Haag Performance has moved to a much larger space in Sacramento to support our engine, transmission, differential and driveline work. The new address is 8230 Belevedere, Suite C, Sacramento, CA 95240. Here’s a couple of photos of the space as we were preparing to move in, look how big it is!

Check us out on Facebook and keep up to date this season.

The E3 Miata of RAMotorsports won the grueling NASA 25 Hours of Thunderhill E3 class with our engine. Congratulations to team owner Ron Alan and all of the drivers for completing 593 laps for a total of 1,779 miles. Check the official results on RaceHero.

We are so proud of Kyle Loustaunau for winning the 2014 NASA West Spec Miata Championship and then winning the Mazda MX-5 Cup shootout. It has been a great ride helping with his racing the last few years.

Congratulations Kyle you are now Mazda’s poster boy!
