Pick your stage, pay the full price. Locks your appointment. Refundable up to 48 hours before.
Drop of the vehcile for your appointment. We pull your factory file, build the map for your exact mods, and flash it in the bay.
After flashing your new tune, we test drive and data-log the vehicle and make sure it's running clean before handing back the keys.
The questions every customer asks the first time. If yours isn't here, call us — (615) 730-8654.
Federal law (Magnuson–Moss Warranty Act) says the dealer has to prove the modification caused the failure before denying a warranty claim. In practice: powertrain warranty is the risk surface. Body, electrical, suspension — unaffected. We can talk through your specific car and what to expect.
For most platforms we tune, the ECU stores a tune-flag the dealer can read. We can usually return-to-stock before a scheduled dealer visit and re-flash after — included free as part of any tune we did. Some BMWs and Porsches log boost/ignition events that persist even after stock-revert; we'll tell you up front if your platform is on that list.
Stage 1 maps on a healthy stock engine, with the recommended fuel, do not blow engines. Our maps are built and proven for safe AFR + ignition timing on every platform we sell. The risk vectors are: skipping the pre-tune health check (we offer one for $129), running the wrong octane, or stacking unsupported mods. We scope all three before you pay.
Stage 1 maps require the octane listed on the tune card (usually 91 or 93). Stage 2 commonly requires 93 + a specific supporting-mod set we'll confirm with you. Run lower octane than spec and the ECU pulls timing to protect the engine — you lose the power you paid for. We don't ship a 93-octane tune to a customer running 87.
Stage 1: 1–2 hours in the bay (read your file → flash your map → quick run-check).
Yes. We keep a copy of your factory file. Stock-revert is free for any platform we tuned — just call ahead and we'll have the file ready when you come in.
A standard flash doesn't include dyno time — it's a separate session. Want real before-and-after pulls on our chassis dyno? Add a dyno session ($349) and you'll leave with a printed sheet of your car's actual HP, torque, and AFR.
We've got tune files for roughly 1,000 engines and only show what we can actually flash. If your car isn't listed, it's not an off-the-shelf flash for us yet. Email us with year, make, model, and engine and we'll quote it.
Stage 1: safe map for stock-or-near-stock cars on pump gas. Stage 2: mapped for supporting mods (intake, downpipe, intercooler, possibly fuel system) — call us to scope.
Full refund up to 48 hours before your appointment. Inside 48 hours it's non-refundable, but you can reschedule to another slot at no charge — we don't charge reschedule fees. Once we've started building your map, it's non-refundable — that work doesn't get undone.
