The Very Spicy Tune Box

The Very Spicy Plaid Tuner Kit

In stock!

Full product walk through and review - DragTimes YouTube video

Turn your low mileage Plaid into a monster with up to 10% more power.

Or give your middle aged Plaid the performance to outrun a brand new one.

The Very Spicy Tune Kit delivers its biggest gains where your rivals expect them the least: high speed acceleration. Above 70 mph the difference is dramatic, transforming the car into an entirely different machine during roll racing and highway pulls.

Example Gains from SirHarrold Development Vehicles:

Benchmark First

Before installing any tune, benchmark your Plaid with a Dragy. Your gains should be measured against your vehicle’s current performance, not against someone else’s car.

Performance varies substantially between Plaids. A high mileage vehicle will not perform like a new one, but it can still see significant improvements.  A battery with significant degradation may not be able to support the full power increase, especially during extended pulls. In those cases, the tune will deliver the maximum power your battery can safely provide. The factory BMS is not modified, and all OEM battery protections remain fully intact.

Features

Installation takes about 15 minutes start to finish.  Video instructions will be provided at time of purchase.  

Remove the system at any time and return the vehicle to stock.

Staging Mode with Persistent Cheetah Stance

The factory Plaid requires approximately 8 to 10 seconds to lower the front suspension and enter Cheetah Stance. Without Staging Mode, the car exits Cheetah Stance the instant both pedals are released to creep into the second staging beam. Once this happens, the entire 8 to 10 second sequence must be repeated.

The driver must either fully stage at the double bulb while waiting for Cheetah Stance, which can upset the driver in the other lane, or wait for the full sequence after the tree drops, resulting in a reaction time of approximately 7 seconds. Neither option works well in competition.

Staging Mode allows the car to enter Cheetah Stance before the second staging beam. You can then release both pedals and creep into the second bulb while the front suspension remains in Cheetah Stance.

On a Pro Tree, there is not enough time to precharge the motors after staging. The driver can launch immediately while retaining the suspension advantage of Cheetah Stance, but without motor precharge.

On a Sportsman Tree, there is enough time to briefly press the brake pedal and then the throttle to precharge the motors. Because the suspension is already lowered, the car can reenter Cheetah Stance in approximately 1.5 seconds before launching.

Power Meter with Advanced Dash and Data Viewer

This adds an additional tab to the Windows app with a more advanced performance dashboard. It captures key metrics such as horsepower, 60 to 130 mph times, and traction control status.

You can log and review advanced vehicle parameters directly on the Windows device or export the data as a CSV file for further analysis. It is a great way to compare stock versus tuned performance or review data after a race to see where the car was limited by traction.

Top Speed Unlock

A separate 203 mph Top Speed Unlock is also available for S Plaid.  This not available for X Plaid.

Additional options can be added here.

Important Information - The Fine Print

This product is intended for off road use only.

Built for experienced drivers operating modified high performance vehicles.

The vehicle’s battery pack should be in excellent condition to support increased power levels. Performance depends heavily on battery health, vehicle condition, and baseline performance.

Performance varies significantly between vehicles. High mileage Plaids and vehicles with battery degradation will not perform the same as newer vehicles, and maximum gains may not be achieved. Always establish a baseline before installing the tune.

The tune increases vehicle power without changing OEM safety limits. High-current spikes, particularly during wheel spin or on rough/uneven surfaces, may trigger the pyro fuse, with risk increasing as the battery ages. For added margin, Plaid Mode is recommended at 7%; 10% should be reserved for smooth drag-strip surfaces, and significantly degraded batteries may require a 9% maximum even at the drag strip. A triggered pyro fuse immediately disconnects the HV battery, resulting in immediate loss of propulsion and requiring a tow. Pyro fuse replacement requires proper high-voltage safety equipment and procedures per the service manual and should be performed by a qualified third party repair facility, not a Tesla Service Center. Customer accepts all associated risks.

Some Tesla battery packs experience cell imbalance. Significant cell imbalance can reduce power output during extended high-load operation, preventing the battery from sustaining factory power levels. Tesla's battery health test does not identify cell imbalance. This is a battery condition, not a result of the tuner. If significant cell imbalance is present, the tuner cannot compensate for it, and performance gains may be reduced or unavailable.

SirHarrold and Mulot regularly release tuner updates to maintain compatibility, and reasonable efforts will be made to restore lost functionality as quickly as possible.  Compatibility with future Tesla over the air (OTA) software updates cannot be guaranteed. Tesla updates may limit, disable, or change tuner functionality without notice.
DO NOT install a TeslaOS update without first confirming that it is compatible with your tuner. Some TeslaOS releases require an update to the tuner app and firmware before they are supported.  TeslaOS cannot be downgraded. Always verify compatibility before installing any Tesla software update. The risk of future Tesla OS incompatibility is low but I prefer to be explicit about this risk.  

Installation or use of this product may affect or void portions of the manufacturer’s warranty. No warranty coverage, express or implied, is provided by SirHarrold or Mulot regarding the effects of installing or using this product.  If preserving your factory warranty is important to you, this product is not recommended.

SirHarrold exclusivly distributes Mulot power tuning products.  Very Spicy is only available on SirHarrold.

This product is VIN locked and licensed for a single vehicle only.

By purchasing or using this product, the customer accepts all responsibility for any damage, injury, costs, losses, or other consequences arising from its installation or use.

High speed driving involves significant risk and should only be performed in a controlled track environment.

Proper tires, wheels, brakes, and brake fluid are essential for high speed operation. All vehicle systems should be thoroughly inspected before every pass.

Even with the proper equipment and preparation, high speed driving remains inherently dangerous. SirHarrold does not represent or imply that this product makes high speed driving safe.

By purchasing or using this product, you acknowledge and accept all risks associated with high speed vehicle operation.

Brake Pedal Feel

Installing the Top Speed firmware changes the brake pedal feel.

Compared to the factory calibration, the brake pedal has a more progressive response with increased pedal travel. Maximum braking force requires additional pedal travel and greater pedal effort than the factory configuration.

Drivers should become familiar with the revised brake pedal feel in a safe environment before operating the vehicle at high speeds or on a race track.
