Remote tuning packages
Every package is delivered and refined entirely online through your Garage — no dyno visit required.
What you'll need

- • A wideband O2 sensor logged in your datalog (we can't tune air/fuel blind)
FAQ
Can you tune E85 on a Terminator X?
Yes — Terminator X, X Max, and Dominator all support flex-fuel and dedicated E85 setups. Tell us your fuel plan during intake and we'll build the tune around it.
What datalogs do you need?
A full-throttle pull from idle through redline (or as far as you're comfortable going) with the standard PIDs logged — AFR, timing, boost/MAP, RPM, TPS, and coolant temp at minimum. We'll tell you exactly what to log during intake.
How many revisions do I get?
Every package lists its included revisions below. Need more? You can request additional revisions from your vehicle page at any time — we'll quote extras beyond what's included in your package.
How long does a revision take?
Turnaround varies by package and is listed below. You'll get an email the moment a revision is delivered.
Do I need to be local?
No — this is 100% remote. You send datalogs, we send tune files, back and forth until it's dialed in.
