DuramaxTuner Diesel Tuners and Turbochargers Now Available at Summit Racing

et more out of your Duramax diesel-powered GM truck with help from the Duramax experts at DuramaxTuner. Summit Racing offers the company’s SPADE Series Tuners for 2011-16 trucks and Stealth Series turbochargers for 2005-16 Duramax-powered trucks.

SPADE Series Tuners
The SPADE (Standalone Programming and Diagnostic Equipment) tuners feature five preset tunes that download to your truck’s ECU via the OBDII diagnostic port:

• Optimized Stock provides a smoother idle than stock and refined timing tables to lower EGTs and improve fuel mileage
• Light Tow adds up to 55 extra horsepower for trucks towing loads under 8,000 pounds
• Heavy Tow adds up to 40 extra horsepower and is recommended for towing loads from 8,000 pounds to the truck’s Gross Vehicle Weight 
• Sport Economy adds up to 100 horsepower and improves throttle response, allows quicker shifts, and lowers average RPM in daily driving situations 
• Race is for maximum performance with engines that have a stock turbo and fuel injectors. It adds up to 135 horsepower yet keeps the EGTs at an acceptable level to prevent damage to the drivetrain. A 150 GPH lift pump is highly recommended 

All SPADE LML tuners feature DuramaxTuner’s Smart EGT Control feature. It smoothly adjusts the proper tables to manage your EGTs automatically—no need to watch your EGTs like a hawk or worry about EGT spikes while downshifting.

This DuramaxTuner video provides more detailed information on each tuning level. 

Stealth Turbo Head Units
DuramaxTuner did its homework developing the Stealth turbos. They feature 7075 billet aluminum compressor wheels that maintain stock part-throttle drivability and spool-up while providing an extra-wide torque curve and horsepower increases. The stock-appearing turbos are pretty much drop-in replacements for the OEM part—your buddies will never know what you’ve got until you take them for a ride. Other features include:
• Genuine IHI or Garrett housings
• Larger, high-flow turbine assembly lowers drive pressure with better balance between boost and exhaust backpressure, maintains lower EGTs under high load
• Liquid-cooled center section with 360 degree thrust bearing
• Anti-surge compressor cover

And surprise-surprise, DuramaxTuner also makes Stealth turbos for 2003-12 Dodge and RAM trucks with the mighty Cummins diesel. Gotta cover your bases.
