JeliBuilt Hydra Custom Tunes

Already own a Power Hungry Performance (PHP) Hydra Chip? Unlock the true potential of your 7.3L Powerstroke with fully custom calibrations written specifically for your truck.

JeliBuilt Performance (Brian Jelich) creates each tune based on your exact hardware and modifications — injectors, turbo, high-pressure oil pump (HPOP), transmission, gear ratio, tire size, and more. These calibrations use the MAP sensor for crisp throttle response, clean fueling, and reduced smoke, delivering excellent drivability whether you’re daily driving, towing heavy, or chasing performance.

Why Choose JeliBuilt Custom Tunes?

• Fully customized to your specific setup (not generic base files)
• Optimized for clean power and better throttle response via MAP sensor utilization
• Fast turnaround — files typically emailed within 1 business day
• Unlimited free revisions for 30 days after delivery
• Easy self-install with free HydraFlash software (or mail your chip in for loading)

Available Custom Calibrations

Choose the number of tunes you need and select from options such as:

• Modified Stock — Clean, low-power calibration that keeps a factory feel while adding refined transmission tuning
• High Idle — Holds elevated idle RPM (you choose; 1100–1200 RPM common) for cold starts, AC, or inverter use
• Quiet Mode / Quiet Idle — Reduces engine clatter at idle for drive-thrus, parking, or quiet operation
• Tow Performance — Light-to-moderate towing with higher shift points and line pressure for crisp, positive shifts and extra power when needed
• Strenuous Tow — Heavy-load focused with optimized fuel and ICP control plus aggressive transmission tuning
• Eco Mileage — Economy-oriented calibration with adjusted timing and shift points for better fuel efficiency
• Daily Driver — Balanced “set-it-and-forget-it” street tune with improved power, response, and smoother operation
• Hot Street — Entry-level performance tune with a noticeable jump in horsepower and torque
• Extreme Street — More aggressive street calibration for snappy throttle and stronger power
• Drag Ripper — Highest-power file in the lineup, optimized for maximum acceleration
