Every tune we deliver is verified on our rolling road. No shortcuts, no assumptions — just the horsepower and throttle response your build deserves.
What We Do
From stock ECU remaps to full turbo conversions, every service at Izzy Performance is executed with the same standard: measured output, verified on the dyno.
Precision calibration of your engine control unit for optimized power, fuel economy, and drivability — tailored to your specific build and driving style.
Our rolling road measures actual wheel horsepower and torque. Every tune is validated with before-and-after graphs so you see exactly what you're getting.
From bolt-on turbos to full custom fabrications. We design, build, and tune forced-induction systems that are both powerful and reliable under sustained load.
Intakes, exhausts, intercoolers, downpipes, and more. We install performance hardware and pair it with a proper tune so every part works as a complete system.
Check-engine lights, misfires, and performance loss — we diagnose the root cause, not the symptom. Honest assessments and clear explanations every time.
Custom exhaust manifolds, intercooler piping, downpipes, and fabrication work that off-the-shelf parts can't handle. Built to your spec, tested to prove it.

About Us
Izzy Performance started with a simple premise: every builder — from the daily driver to the track car — deserves a tune that's measured, not assumed.
Located on South Main Street in Gardena, we've spent years refining our craft on the dyno and in the bay. We don't chase numbers for the sake of them; we chase the right numbers — the ones that make your car faster, more responsive, and safer to drive.

How It Works
A straightforward process designed around your goals — not ours.
Tell us about your car, your goals, and how you drive. We'll recommend the right approach — whether that's a simple tune or a full build.
We inspect your vehicle, read existing codes, and assess what hardware you're running. Then we map out a plan with clear expectations.
Whether it's a software tune or a mechanical build, we execute with care. Every adjustment is monitored and logged.
Your car goes on the rolling road. We verify the results, fine-tune as needed, and hand you the keys with confidence.
