M77 Performance Life-Time E-Tune

Maximum flexibility. Unlimited updates.
This package gives you full lifetime support for two fuel types — perfect for enthusiasts running both pump gas and ethanol blends (like 93 & E85). Whether you're starting with bolt-ons or planning a full build, this is the most complete tuning option we offer.
 
What’s included:
– Two fully custom tunes (e.g., 93 + E85, 93 + E30)
– Unlimited revisions and retunes for both fuels
– Full datalog review & support with every update
– Tune delivery via email (typically 2–4 business days)
– Priority access to support and faster turnaround times
 
Unlimited Updates for Both Fuels:
As your build evolves — from bolt-ons to big turbo — we’ve got you covered. Simply submit a new intake form any time you change parts, and we’ll update both tunes as needed.
 
Requirements:
– Laptop with Windows or macOS
– OpenPort 2.0 or similar adapter
– Stable internet connection
– Wideband strongly recommended for ethanol tuning
– Safe, mechanically sound vehicle
 
Who This Is For:
– You daily drive on one fuel but race on another
– You want to future-proof your build with unlimited updates
– You hate paying $100 every time you change a part
