Welcome to tjituning.com

TJI Tuning is a side project I'm working on. I have experience with, and offer performance 

tuning services to a limited number of vehicles and standalone units in the Colorado 

Springs, CO area. 

 

 These vehicles include: 

  • Most 2002 and later Subaru vehicles
  • Evo 5 and later Mitsubishi vehicles
  • HP Tuners capable vehicles: LS1, LS2 and now including Duramax diesel applications!
  • Please contact in regards to other vehicles (depends on standalone units below)

These Standalones include: 
  • SDS (Simple Digital Systems)
  • Fast XFI
  • Megasquirt
  • Electromotive
  • Turbo XS UTEC (user tunable engine computer for Subaru/Mitsubishi/350z, acts similiar to a standalone)
 
 
*Over 2 years of experiance with load based tuning including: big MAF, blow through MAF, MAP based speed density, and E85 setups. (now including Duramax diesel tuning)
I don't claim to be a professional tuner, but I can offer a solid, application based custom tune for a fair price. Contact me here for details.
