Helpful Notes

• Edge Comp RPM fueling: Levels 4–5 target more RPM with full fueling than earlier devices; competition setups commonly carry power toward ~4,000 RPM with proper wire-tap, lift pump supply, and turbo/injector support.
• Wire-tap install: The Comp’s fueling control requires a correct pump wire-tap; follow the manual exactly.
• Monitor first: Add EGT and fuel pressure to protect pistons and the VP44 (12–15 PSI cruise; avoid low PSI).
• Emissions/usage: Verify local/track rules; some settings and devices are for competition/off-road use.

Frequently Asked Questions

What makes the EDGE Comp different from a handheld programmer?

Edge Comp is an inline, wire-tap module that directly commands fueling/timing on the VP44 for stronger, higher-RPM delivery, while handhelds (e.g., Smarty S03) reflash ECU parameters. Many competitors choose Comp for sled pulling/drag racing.

Can the Comp help me pull past 3,000 RPM?

Yes—its higher-RPM fueling strategy is designed for extended fueling in upper power levels; with the right turbo, injectors, lift pump, and gearing, trucks are commonly set up to carry power toward ~4,000 RPM for competition use.

Do I need to monitor EGT and fuel pressure?

Absolutely. Use an Insight CTS3 with EAS and an EGT probe, and add the BD low fuel-pressure alarm to protect the VP44.

Juice w/ Attitude vs. Comp—how do I choose?

Juice CTS3 bundles tuning + a great monitor and is outstanding for street/tow. Comp is a wire-tap competition module favored where maximum fueling and RPM extension are desired.

Will these work on both early (’98.5–’00) and late (’01–’02) VP44 trucks?

Yes—just select the correct SKU (e.g., Comp 30305 for ’98.5–’00, 30306 for ’01–’02; Juice CTS3 31500-3 vs 31501-3).
