2016+ Cadillac ATS/CTS - Without HP Tuners

2016+ Cadillac ATS/CTS – Without HP Tuners

Unlock the full potential of your ATS or CTS with a custom remote tune that works with the HP Tuners hardware you already own — no bundled credits, no upsells, just a calibration built specifically for your car.

What's Included in This Tuning Service

Throttle & Drivability Calibration

• Dramatically reduced throttle lag and surge on takeoff
• Eliminated dead-pedal feel while cruising
• Distinct, properly tuned throttle response in both Touring and Sport modes
• No external throttle booster required — ever

2016-Specific Transmission Tuning

• Fully rewritten shift points for Touring mode — reduces bog and improves flow
• True Sport Shift Mode that holds gears longer and completes shifts more quickly than Touring

Engine & Platform Options

• Displacement on Demand (DOD/AFM) disable available
• Raised rev limiter in Park and Neutral
• Compatible with Overkill Supercharger Kits

How the Remote Tuning Process Works

1. Download VCM Suite from hptuners.com/downloads and connect your HP Tuners interface to your vehicle.
2. Read your stock ECM tune and save it — label it "yourname stock read" — and do not read the FPCM module. Leave that box checked as "Do Not Read" to avoid spending 2 extra credits.
3. Load the provided LFX scan config file in the Scanner, complete a 5–10 minute drive, and save the datalog as "yourname Stock Drive Log".
4. Email both files — your stock read and your drive log — to Tracy Lewis Performance.
5. Receive your revised tune file, flash it, complete another drive log, and send it back. The process typically takes 2–3 iterations to dial in your individual car perfectly.

Credit note: 2016+ Cadillac ATS/CTS vehicles require 4 HP Tuners credits for the ECM and 4 additional credits for the TCM, for 8 total. Credits must be purchased separately — this service provides the custom tune file and calibration expertise, not the credits.

Stop settling for generic throttle boosters and one-size-fits-all flash tunes — this is a custom calibration built around your actual car, your mods, and your driving.
