Frequently Asked Questions
Questions we get asked most
A street tune typically takes one full day. Stage 2 builds with TCU mapping may run into a second day. Full builds or complex platforms can take longer — we'll give you a realistic timeline before you drop off.
This is the most common concern we hear, and it's a fair one. Under the Magnuson-Moss Warranty Act, a dealer cannot void your warranty simply because you've had an aftermarket tune — they must prove the tune directly caused the issue in question. That said, every situation is different. We'll walk you through exactly what to expect for your specific car and build before we touch anything.
An off-the-shelf flash is a pre-built map designed for an average car in average conditions. A dyno tune is built live on your specific car — accounting for your mods, your altitude, your fuel, and your goals. The difference shows up in both power numbers and long-term reliability.
A generic flash applies a pre-built map from a database — it's designed for the average car under average conditions. A dyno tune is developed and validated live on your specific car, accounting for your mods, your climate, your fuel, and your goals. Every tune we deliver is proven on our in-house dyno before you drive it. That's the difference between a number on a printout and power you can actually trust.
No. A Stage 1 street tune is written for your stock car and delivers real gains with no hardware changes required. If you're planning mods, we can discuss the best sequence so your tune and parts work together from the start.
We write tunes for 91 octane, 93 octane, E30, E85, and flex fuel configurations depending on your setup and goals. We'll discuss the best option for your car during the consultation.
