Clean Power With Smart Calibration Built In

Behind the wheel, it may feel simple, but there’s serious engineering at work under the hood. The Street Tune is the result of over 100 custom calibration changes built to work seamlessly with your truck’s stock components and emissions equipment. It uses SMART EGT control and optimized air-fuel ratio mapping to keep soot production low while improving drivability across the board. You’ll get a clean, strong powerband that responds exactly how it should, no dead pedal, no hesitation. This tune is built for trucks that tow occasionally or rarely, offering safe performance that keeps EGTs in check and reliability intact. It’s a great choice if you’re running a stock truck with minor upgrades and want to get the most out of it without stepping into risky territory. Because it uses EFI Live SPADE hardware, you also gain access to datalogging, diagnostics, and easy tune updates over time. It’s smart tuning designed to deliver real-world results with long-term peace of mind.
