Dan is top notch. He has tunes both my cars. 2005 v6 auto with a vortech and my current 2008 GT that was running a 75 shot.

Q. What makes a Realspeed tune better?
A. A Realspeed tune is much more than a quick “tweak” of your car. We thorougly go over your car and your computer’s calibration and take the time to do the extra steps required for the best possible result. Full throttle, part throttle, idle, transient fuel (tip-in) and cold-start parameters are tuned.
1) Realspeed does a complete 30 point MAF Transfer calibration mapping, not just full throttle like some other tuners
2) Realspeed is an SCT tuning software Certified Tuner. We are certified at their highest “Calibrator” level through SCT’s Advanced Dealer Training Program. This gives us access to parts of the tuning software that most SCT dealers don't have.
3) Dyno tuning is done on our state-of the art Mustang MD1100-SE Dyno. The Mustang dyno incorporates an eddy-current load controller to simulate the actual combined aerodynamic drag, rolling friction, and vehicle inertia (weight) the vehicle experiences while driving on the street or racetrack. This allows for more accurate tuning under conditions that match the real world. These conditions can not be simulated by an inertia-only dyno.
4) Our wideband Air/Fuel (A/F) Ratio gauge inserted in the midpipe, not the tailpipe, for more accurate A/F readings
5) Our Wideband Air/Fuel sensor is calibrated before each tune
6) We use a more accurate and more expensive NTK wideband A/F sensor for tuning instead of cheaper and less durable Bosch sensors
7) Fuel pressure is checked and/or set. Timing is checked & set. Spark plugs are checked for the correct type & heat range. The O2 sensors are checked to make sure they are working correctly. The ACT & coolant temp sensors are checked to ensure they are working.
8) 1986-1995 Mustang sensor functions and computer outputs are data-logged with our exclusive in-line signal scanner to read computer data that many other shops can’t get
9) 1996-2010 Mustangs are data-logged with SCT Live-Link software to see & record computer inputs & outputs in real time.
10) Each car is tuned until the car is right, with no pre-set time limit or “rush-jobs”
11) Realspeed is Vortech Superchargers Top-Tier Installer. We are recommended by Vortech for tuning their superchargers. We have almost 20 years experience with Vortech superchargers.
