Product Description
Michigan Motorsports Email Tune | LS & Gen V LT GM V8 Custom Calibration Service
Fast, Affordable Remote Tuning for 1997+ GM LS & LT Vehicles (HP Tuners Required)
Once you start adding performance parts to your GM LS or LT-based vehicle—especially a camshaft package—your PCM calibration becomes the difference between “it runs” and “it runs right.” The Michigan Motorsports Email Tune is the fastest and most cost-effective way to get a custom calibration built around your exact combo in a few simple steps.
After purchase, we’ll send you a questionnaire to capture your vehicle details and all modifications. You’ll then email your current file to tunes@michiganmotorsports.com along with your completed questionnaire. Our calibrations are designed to improve drivability, throttle response, and overall performance while keeping that stock-like manners you want on a street-driven build.
Important: You must have your own HP Tuners interface to read/write the PCM (MPVI2, MPVI3, or MPVI4). Most vehicles typically require 2 credits (some 2017+ models may require more). Credits are not included.
Key Features & Benefits
- Custom Calibration for Your Mod List: Built from your questionnaire and current tune file to match camshafts, bolt-ons, fueling changes, and driveline setup.
- Improved Power & Drivability: Performance-focused calibration designed to maximize performance and mileage while retaining smooth, stock-like street manners.
- Sharper Throttle Response: Reworks key calibration parameters to eliminate the lazy feel found in many stock files.
- Transmission Optimization Available: Shift scheduling, shift firmness, converter behavior, and shift points refined to better match performance parts and extended RPM ranges.
- Fast Remote Process: Simple email-based workflow—no shop visit required.
What’s Optimized in Each Calibration
- MAF & VE Modeling: Mass Air Flow and Volumetric Efficiency tables optimized for accurate airflow calculation and consistent fueling.
- Air/Fuel Ratio Targets: Wide open throttle fueling refined for safe, repeatable power.
- Ethanol Blend Compensation: Stoichiometric ratio configured for typical pump fuel ethanol blends.
- Ignition Timing Strategy: Timing tables calibrated efficiently for 87, 89, or 91–93 octane fuels (premium fuel allows the most aggressive timing strategy).
- Idle & Part-Throttle Control: Airflow, fueling, and timing refined—especially important for camshaft and internal engine modifications.
- Torque Management Refinement: Torque management tables relaxed where appropriate to reduce factory performance limitations.
- Transmission Calibration: Eliminates lazy shift behavior, improves shift feel, adjusts shift points for higher RPM builds, and optimizes converter tables for aftermarket stall converters.

Email Tune
Customer service is amazing! Currently getting assistance tuning my turbo 6.0L and they definitely have delivered. First base tune to get the truck running worked well. Since the base tune I’ve sent a few logs back and they were adjusted to better fit my setup. Quality tunes and in the timeframe it took to receive it (especially over the holiday weekend) I’m blown away!
