What We Install

Magnuson TVS1900 Install

The benchmark for naturally-aspirated Toyota platforms. We've installed dozens.

ECU Programming & Tuning

Hand-held programmer, dyno-validated tunes, follow-up on the first 500 miles.

Supporting Mods

Upgraded fuel pumps, intercooler service, exhaust matching, drivetrain checks.

Altitude Tuning

Front Range altitude eats power. A blower restores what physics took. We tune for your elevation profile.

Pre-Install Inspection

We inspect the long block, cooling system, and fuel system before approving any forced-induction install.

Post-Install Support

First-500-mile check-in. Re-torque, scan, validate. Included in the install.

What To Expect

Your install in four steps.

1. Schedule online. Pick a date and time through our online scheduler. Same-day appointments often available.

2. Drop off. Bring your rig to our Lakewood shop. We review the build with you and confirm timing before any work starts.

3. Install. Our certified techs handle every step in-house. Most lift kits are completed in a single shop day.

4. Pickup. Road test, torque check, and alignment before your keys go back in your hand.

Frequently Asked Questions

On a stock 5th Gen 4Runner V6, expect roughly 75 to 90 horsepower at the wheels with the standard tune. Tundra V8 platforms see bigger gains. The exact number depends on altitude, exhaust, and fuel.

Yes, on the powertrain. A supercharger is a major modification and Toyota will deny powertrain claims after install. Magnuson offers their own warranty on the kit. We're upfront about this at drop-off so you go in clear-eyed.

Yes, on a healthy long block with healthy cooling. We require a pre-install inspection to confirm the engine, fuel system, and cooling are in shape. Marginal candidates (older, neglected, or already heat-soaked) get flagged before we take the job.

Yes. Magnuson tunes assume 91 octane minimum. 93 if you can get it. Skipping premium will pull timing and erase the gain you paid for.

Typically 2-3 shop days. Day 1 is teardown and install, Day 2 is programming and dyno time, Day 3 is shakedown and the post-install inspection. We confirm the schedule at drop-off.

Yes, on Tacomas with the 1GR-FE V6. The 4-cylinder Tacoma is not a Magnuson candidate. Bring us the year and engine and we will confirm fitment before you order anything.
