Tuneless vs EFILive

Built for Holley Sniper.
Unlimited tunes, not per-VIN.

EFILive is a GM-focused tuning tool licensed per vehicle (per VIN). Tuneless is built around Holley Sniper EFI specifically, with unlimited tune sessions on your vehicle for as long as you're subscribed.

Where they differ

EFILive licenses at $125 per VIN, with no visible free tier — you pay before you see what the software finds on your engine. Tuneless has a free read-only tier (live telemetry, diagnostics, no writes) so you can check compatibility and see real data from your own Sniper before paying anything.

EFILive's tooling is built around GM ECU platforms. Tuneless targets Holley Sniper 1 and Sniper 2 specifically — hardware that ends up on GM, Ford, and Mopar-based restomods and LS-swap builds alike — with a guided road-tune wizard and plain-English diagnostics rather than raw table access.
