Services at PSI Motorsports

PSI Motorsports is known for selling and installing performance upgrades on some of the fastest Ford vehicles in Texas.

PSI Motorsports employs highly trained technicians with years of experience in the performance industry. All of our technicians are certified by Ford Motor Company.

We are NOT just "parts changers" like most of our competitors. We design custom packages from the ground up using our numerous years of performance vehicle modification background. We only use the parts that work. We are not here to sell you parts that can't back up there claims like most of our online competitors.

So if you're looking for a little extra power or an all-out 700+ rwhp beast, we've got you covered. Feel free to browse the website in search for your performance parts needs. If there is a part you’re having trouble finding, feel free to call us at 281-557-2874 or email us at  

Custom Dyno Tuning and Dyno Time

PSI Motorsports offers some of the best tuning for most modified Ford vehicles. Tuning from PSI is known to be some of the best in the state of Texas and surrounding states. PSI Motorsports has built its reputation on building and tuning some of the fastest street driven vehicles.

We are here to get the most out of your vehicle without sacrificing your drivability. We offer SCT Tuning for most '99 and newer Ford Vehicles.

PSI also offers dyno testing on our Dynojet 248C 1500rwhp in-ground chassis dyno. You can see rwhp, rwtq and air fuel ratio to see exactly where you're at.

Sorry, but no walk-ins will be accepted for dyno tuning. Dyno tuning is set up by appointment only.

Below is a check list that should be followed before bringing your vehicle in for tuning.

Dyno Check List:

1.     All vehicles need to arrive with the desired fuel for tuning.

2.     Tuning for multiple fuels is available.

3.     Vehicles should arrive with at least 1/4 tank of gas.

4.     Ensure that there are no fluid leaks of any type (oil, coolant, trans, etc.)

5.     The correct spark plugs are installed and gapped correctly for your application. (if you are unsure of the proper gap please call.)

6.     Wiring needs to be complete with no shorts, or loose connections.

7.     Battery and alternator need to be functioning correctly.

8.     Vehicles will not be dynoed with any engine trouble codes present. If your CHECK ENGINE light is on let us know before your appointment.

9.     2003-2004 Cobra and 1999-2004 Lightning/Harley: Make sure your intercooler pump is operating properly.

10.   No drivetrain vibrations should be present. Drivetrain vibrations are amplified on the dyno and vehicles with excessive vibration will not be dynoed.

11.   No repairs will be performed while vehicle is on the dyno. Vehicles will have to be removed from dyno and repaired before tuning can continue.
