Performance Upgrades

ECU tuning, exhaust upgrades, intake systems, and suspension modifications for Audi and VW. We build cars that are faster, handle better, and still reliable enough to daily drive.

What We Build

Performance Without Compromise

We don't just bolt on parts — we build complete packages that work together. Every modification is installed properly, tested, and backed by our expertise in Audi and VW platforms.

Audi performance upgrades at Reflex Automotive

ECU Tuning & Software

Stage 1, Stage 2, and custom tunes for more power, better throttle response, and improved drivability. We are an authorized APR and United Motorsport dealer for Audi and VW platforms.

Exhaust, Intake & Bolt-On Parts

Downpipes, cat-back exhaust systems, cold air intakes, and intercooler upgrades. We are an ECS Tuning dealer -- we can source and install the right bolt-on parts for your build.

Suspension & Handling

Coilovers, sway bars, bushings, and brake upgrades for track days or spirited driving. We set up and align everything after installation.

Built to Last

Performance parts installed correctly last. We torque to spec, use proper hardware, and test everything before your car leaves. No shortcuts.

Daily Drivers Welcome
Performance You Can Live With

Not every build is a race car. Most of our performance work is for daily drivers who want more power, a better exhaust note, and improved handling — without sacrificing reliability or comfort. We'll help you find the right balance.

Great experience! Not enough space to outline all the ways that I felt Heather and her team delivered on their promise of great service at a fair price. Heather worked with me to find solutions that worked for what I was trying to accomplish performance wise and went the extra mile to offer services that were preventative.

FAQ

Performance Upgrade Questions, Answered

This is worth discussing carefully. Under the Magnuson-Moss Warranty Act, a manufacturer cannot void your entire warranty just because you installed an aftermarket part. However, they can deny a specific warranty claim if they can demonstrate that the modification caused the failure. For example, a tune could be grounds for denying an engine or transmission claim. We'll walk you through the specifics for your vehicle so you can make an informed decision. Learn more about warranty protection.
Stage 1 is a software-only tune — no hardware changes required. It optimizes boost, fueling, and timing within the limits of your stock hardware for a noticeable increase in power and throttle response. Stage 2 adds supporting hardware — typically a downpipe and sometimes an intake or intercooler — which allows the tune to push further. Stage 2 makes more power but requires more investment and commitment. We'll help you decide which stage fits your goals.
We prefer to source parts ourselves for warranty and quality reasons. When we supply the part, we can stand behind the entire job — parts and labor — backed by our 3-year / 36,000-mile warranty. Customer-supplied parts carry more risk: wrong part numbers, missing hardware, or quality issues we can't control. That said, we'll discuss it on a case-by-case basis — call us at (603) 207-4004 and we'll give you a straight answer.
Our tuning focus is Audi and VW platforms — that's where our deepest experience and tuning partnerships are. For other makes, we can handle bolt-on modifications like exhaust, intake, and suspension work, but we'll refer you to a specialist for ECU tuning on non-VAG platforms. Learn more about our Audi service and Volkswagen service.
