Give us a quick call at 636-429-7020 or message us to schedule a visit — we’ll make sure the parts are ready when you arrive.

How do I know if this part fits my vehicle?

Unsure if it’ll fit? No problem — that’s what we’re here for. Send us your vehicle’s year, make, and model, and we’ll verify fitment before you order. We can also point you toward compatible upgrades or supporting parts if needed.

What if I need to return a product or it’s defective?

Most unused items can be returned within 30 days in their original packaging. Some products are covered by a manufacturer’s warranty as well. If something arrives damaged or doesn’t meet your expectations, just let us know — we’ll help you get it replaced, refunded, or repaired. (Tracking updates are also emailed automatically once your order ships.)

What's the lead time on custom or fabricated parts?

Many of our parts are built to order — especially fabricated or performance components. These can take additional time to produce before shipping. Lead times vary by manufacturer and demand, but we’ll always keep you updated along the way. If you’re working on a tight schedule, reach out before ordering at 636-429-7020 and we’ll confirm current availability or estimated ship dates.

Description

The Boost Control Module instructs the vehicle's ECU to increase the amount of pressure in the manifold to a higher level before releasing it through the wastegate, keeping more boost available for when you need it (up to an estimate 49 horsepower and 82 lb./ft. of torque). The module reads the MAP (manifold air pressure), preventing over-boost and ensuring that power is added safely. Everything you need to set up your Boost Control Module, including the control module, wiring harness, and complete instructions are included. Featuring easy plug & play installation, it can typically be installed and ready to use in 30 minutes or less!
