What to Monitor on a 5.9L (03–07)

• EGT (pyrometer): Safeguards pistons/turbos under load or towing—add via EAS 98620 kit.
• Boost: Confirms turbo health and tune behavior.
• Transmission temperature: Critical for 48RE longevity on grades and hot climates.
• Fuel pressure (low-side): Verifies lift-pump supply; integrate with CTS3 using 98605 + 98607.
• Rail pressure: Viewable over OBD-II on the CTS3 for quick diagnostics.

Tech Notes & Fitment

• Year splits: Some pods are 03–05 only; others span 03–07 or 03–08—match the year range on the product page.
• Senders & scaling: When adding analog sensors to the CTS3, wire through the EAS Universal Sensor Input and select correct scaling in the setup.
• Clean installs: Use pillar/dash/overhead pods for visibility without blocking airbags or vents; secure wiring away from sharp edges and heat.

Frequently Asked Questions

Do I need a pyrometer if I’m stock?

It’s still recommended for towing—EGTs can climb quickly on long grades. Add the EAS 98620 to your CTS3 for accurate EGTs.

How do I log low-side fuel pressure on a CTS3?

Use the EAS 98605 with the 0–100 PSI sensor (98607), then configure the channel and units in the monitor.

Which pod gives the cleanest look in an 03–07 Ram?

For digital monitors, the Edge 38406 pillar pod is a favorite. For multiple analog gauges, see Banks 63319 dash (03–05) or the Banks 63367 overhead (03–07).
