HP Tuners is a long-standing desktop tuning tool built for a broad range of ECUs. Tuneless is a browser-based tool built specifically for Holley Sniper EFI, with a guided wizard instead of manual tables.
HP Tuners runs as installed desktop software with a hardware interface and a per-vehicle credits model. Tuneless runs in a Chrome or Edge tab over WebUSB — no install, no drivers, and no credits to buy before you can read your engine.
HP Tuners covers a wide range of GM, Ford, and Dodge platforms for tuners who work across many ECU families. Tuneless is focused specifically on Holley Sniper 1 and Sniper 2 EFI, with a guided road-tune wizard (idle, cruise, throttle, decel, cold-start) built around that hardware, plain-English diagnostics, and an AI tuner (Jules) you can ask about what a symptom means.
