Complete Tuning Solutions offers remote and in-person tuning solutions for most aftermarket standalone engine management systems, Original Equipment Manufacturer Engine Computer Modules, and the majority of aftermarket wire in “piggyback” applications available today.

I also offer vehicle build and consulting services. Over 20 years of engine and chassis tuning experience with concentrated expertise in forced induction and nitrous oxide applications.  Experience includes drag racing, autocross, road racing, rally, street, and drift applications.


I started tuning in 2000 with the DSM (Diamond Star Motors- 4G63, 4G64) platform.  Experience quickly expanded to the 3000GT/Stealth communities (6G72/6G74).

By 2006 Toyota (1JZ, 2JZ, 3SGTE, 7M), Mazda (KL-DE, KL-ZE, MZR DISI) , Nissan (VQ30DETT, RB20DET), Subaru (EJ20x, EJ25x), Rotary (13B, 12A) and finally LS GM engine based platforms were supported.

Since 2006 I have continued to expand my knowledge by working with Turbocharged Viper applications (Gen 2), Audi (1.8, 2.5), BMW (S85, M57).
