Twin turbo performance engine at INF Performance Chicago
SVC — 02 / PERFORMANCE UPGRADES

MORE POWER.
ENGINEERED
RIGHT.

From Stage 1 ECU tunes to full forced induction builds — we extract every horsepower your platform has to offer, safely and reliably.

Performance upgrades done wrong are expensive failures. Done right, they transform how a car drives — on the street and on track. At INF Performance, every upgrade is matched to the platform, paired with supporting modifications, and validated on the road. We build cars that perform and stay together.

WHAT'S INCLUDED

PERFORMANCE UPGRADE SERVICES

  • ECU TUNING & REMAPPING
    Stage 1, 2, and 3 ECU tunes for turbocharged and naturally aspirated platforms. We work with reputable tune files and custom maps — optimizing ignition timing, boost, fueling, and throttle response for your exact modifications.
  • TURBO & FORCED INDUCTION UPGRADES
    Upgraded turbos, intercoolers, blow-off valves, intake piping, and full turbo kit installations. We build forced induction systems that are reliable on street-driven cars — not just dyno queens.
  • INTAKE & EXHAUST SYSTEMS
    High-flow air intakes, downpipes, catbacks, and full exhaust system fabrication. We spec exhaust systems for your goals — whether that's max power, a specific sound level, or passing emissions in Illinois.
  • SUSPENSION & HANDLING UPGRADES
    Coilovers, sway bars, strut braces, alignment, and corner balancing. We set up suspension for your driving style — from a lower daily driver to a properly sorted track car with real alignment specs.
  • BRAKE SYSTEM UPGRADES
    Big brake kit installation, brake line replacement with stainless braided lines, track-spec brake fluid, and pad upgrades. If you're adding power, your brakes need to match it.
  • FUELING SYSTEM UPGRADES
    High-flow fuel pumps, injector upgrades, fuel pressure regulators, and port injection additions for direct injection platforms. Fueling is the foundation of any serious power build.
  • TRACK & PRE-EVENT PREP
    Full pre-track inspection: brakes, fluids, suspension torque checks, safety equipment review. We make sure your car is ready for the demands of track driving — not just the daily commute.
THE INF APPROACH
01
ENGINEERED, NOT GUESSED
Every upgrade is matched to the platform and paired with the supporting modifications it needs. Power without proper fueling, cooling, and chassis work is a liability.
02
STREET-RELIABLE BUILDS
We build performance cars that start every morning, pass emissions, and live 80,000 more miles. Reliability isn't optional — it's the standard we hold every build to.
03
YOUR BUILD, YOUR GOALS
We start by understanding what you want the car to do — daily driver, weekend track car, show car — and spec the build to match. No generic part lists.
