Great Experience with Grizzly Tuning!! Trevor responded to my inquiry very quickly and made himself available to help answer a few questions i had. Because of that level of customer service i setup a tune with him!! Even after the tune session he followed up asking how the car was performing. I told him i needed to be faster, now i am saving for a new setup! I will have the fastest corvette on long island with grizzly tuning in my corner! Thanks Trevor!!

FAQ
FREQUENTLY ASKED QUESTIONS
You bring your car in, we load it on the dyno, and we make small adjustments to your ECU map while monitoring performance in real time. We test fuel, ignition timing, boost pressure (if you have it), and other parameters until the engine runs strong across the RPM range. You see the before-and-after numbers, and we walk you through what changed and why.
Yes. We tune for whatever fuel you run: pump gas, premium, E85, or a blend. The tune is specific to your fuel choice, so the engine runs optimally on what you put in. If you ever switch fuels, let us know so we can adjust the map if needed.
Yes. If you have a turbo or supercharger, we integrate it into the tune, handle boost control, and solve any electrical or cold-start issues that come with the modification. We dial it in for reliability and power together.
A typical tune is a few hours, depending on how much testing and adjustment your car needs. Complex builds or electrical troubleshooting can take longer. Call for an honest estimate based on what you're bringing in.
Often yes. We run full diagnostics to find the fault code, solve the problem, and get the car running smooth. Many issues are electrical quirks or sensor problems that we can resolve during a tune session.

Serving Bohemia
Bohemia sits in the Town of Islip in central Suffolk County, a mix of residential streets, commercial strips along Veterans Memorial Highway, and industrial parks near Long Island MacArthur Airport. Most driving here is a blend of local roads and highway runs on Sunrise Highway and the Long Island Expressway, so engines see both stop-and-go traffic and steady cruising. Long Island winters bring cold mornings and salted roads, and summers bring heat and humidity that raise intake air temperatures. A good tune has to handle all of it: clean cold starts in January, stable timing on a humid August night, and smooth part-throttle manners in traffic.

Why Bohemia customers need this work
A tune is only as good as how the car drives the rest of the week. In Bohemia that means a map that starts clean on a cold morning, stays smooth in traffic on Veterans Memorial Highway, and holds safe timing when intake temperatures climb in summer. We build that on the dyno, where we can load the engine, log air-fuel ratio and knock, and adjust fuel and ignition step by step. If you add parts later, such as a bigger turbo, injectors or a fuel change to E85, the tune needs to change with them.
