    The SPADE (Standalone Programming And Diagnostic Equipment) makes the highest quality tunes on the market available in a simple to use OBD style flash tool. The tunes represent the best in drive-ability, reliability, and power. The SPADE system is the first hardware to ship pre-loaded with tunes of this caliber.  Requires no emailing, laptop usage or other tomfoolery. 

    The SPADE has the ability to scan trouble codes and log data for analysis. The Jack SPADE is designed to maximize performance retain reliability on trucks equipped with a stock transmission.

    Power Levels for 2001-2005 Trucks: 

    1. Optimized Stock Power delivery smoother than stock with near stock output -Refined timing tables for lower EGTs and higher efficiency

    2. Heavy Tow Tune +40rwhp over stock- Refined timing tables for lower EGTs- Throttle pedal revised for simplified low-speed trailer maneuvering- Built for towing loads from 8000lbs to gross vehicle weight. 

    3. Light Tow Tune +60rwhp over stock -Refined timing tables for lower EGTs -Throttle pedal revised for simplified low-speed trailer maneuvering -Built for towing loads under 8000lbs

    4. Sport Econ +80rwhp over stock -Best balance of power reliability and efficiency for unloaded daily driving -Low smoke output -Throttle sensitivity increased for less throttle input, quicker shifting and less average RPM in daily driving situations

    5. Stock Trans Race Tune +100rwhp over stock –Maximum horsepower tune for stock transmission- If abused, has the potential to shorten the life of your stock transmission –Typically will run mid 14’s near 93 MPH on a truck set up for drag racing

    *2004.5 and up models feature turbine braking feature which adds up to 120 brake HP through manipulation of the turbocharger vanes while decelerating with a load.  Keep the heat off your brakes on those long grades!

    Using TCM tuning in conjunction with our ECM tuning yields the ultimate combo for consistency and driveability.  Our updates improve torque converter clutch engagement routines, improve shift feel and minimize defuel.  This product is recommended on all Duramax trucks equipped with the Allison trans.

    Includes: Valve, Clamps, and Instructions

    *For use on '01-04 VIN 1 LB7 Trucks only

    Fass 165 Lift Pump

    From the factory, the Duramax trucks are not equipped with a pump to push diesel fuel from the tank to the engine.  This pump ensures there's always a strong supply of clean diesel fuel to your high-pressure fuel system.  Includes a filter and water separator for additional fuel system protection.  This pump is mandatory on our higher horsepower applications where fuel starvation can cause a lack of power, poor shifting, and excessive smoke from low fuel rail pressure. 

    Designed for light-duty trucks while utilizing all the best features of the HD series. Built into a smaller compact version, the Titanium Series offers flow rates up to 260gph. This size difference allows you to tuck the pump closer to the frame for better clearance and less visibility without sacrificing any of the features known to FASS systems. The same motor used on the HD Series (class 8 applications) is also used on our Titanium Series, proving once again that quality is #1 at FASS. *Made in the USA *Lifetime Warranty Available*

    Edge Insight CTS2 Monitor

    The Only Gauge Display You'll Ever Need! As far as gauges go, this unit is the most compact and comprehensive piece we've found. It allows users to set up a personalized gauge screen based on the feedback they want to see.

    The user can have as many as 8 gauges (or as few as 3) displaying real-time data from the OBD2 port at once

    FloPro Exhaust

    4" or 5" Exhaust with or without a muffler. 

    Flo Pro products are made from 16ga mandrel bent steel. They offer both aluminized and T409 stainless steel exhaust systems. They have one of the most diverse products on the market. Flo Pro has direct fit exhaust kits for your Duramax! With all pre-bent and pre-welded hangers, you never have to guess where a pipe goes. Everything just fits right into place.


    We don't just provide custom tuning and manufacture turbos, we also offer a full-service diesel performance shop.  Customers from all over the country have chosen to trust us building their dream trucks.  We take that very seriously.  Meeting deadlines with the job done correctly seem like a simple request, but if you have had performance work done on a diesel truck in the past you know that is not always the case.
