CT5 stage 1 tune delivers 280 wheel horsepower, with a 0-100km/h acceleration time under 5 seconds. The Cadillac CT5 is a mid-size sedan under the Cadillac brand. Based on SAIC-GM's "Second Engine" strategy, the new vehicle inherits the original rich configurations while upgrading the entire lineup with the new-generation Cadillac Mobile Internet Experience CUE and wireless CarPlay. The top-tier Platinum Sport model additionally features the Baidu Intelligent Voice Interaction System. Below are the details of the CT5: 1. Body dimensions: The new vehicle measures 4924/1883/1453 (1445) mm in length, width, and height, with a wheelbase of 2947mm. 2. Powertrain: The domestically produced Cadillac CT5 is equipped with a 2.0T variable-cylinder turbocharged engine, delivering a maximum power of 174KW and a peak torque of 350 N·m, while meeting the China VI emission standards. The transmission system is paired with a 10-speed automatic manual transmission.
I just got a Stage 1 ECU tune for my CT5, gaining roughly 25-30 horsepower. The stock engine had 237 hp, and now it feels like it's pushing over 260. The whole process was pretty straightforward—I went to a professional tuning shop where they reprogrammed the ECU via computer without touching any hardware. It took about half a day. The difference was noticeable right after starting it up: quicker throttle response, much stronger acceleration, and easier high-speed overtaking. Fuel consumption increased slightly, about 5% more in city driving, but overall it's worth it, especially for car enthusiasts. Just a heads-up: always go to a reputable shop and avoid DIY attempts to prevent malfunctions and warranty issues.
I've been doing car modifications for many years and have handled numerous first-stage ECU tuning for the CT5. This level of tuning mainly optimizes fuel injection and turbocharger settings without involving hardware modifications. The standard 2.0T version can increase horsepower from 237 to around 270, with an improvement range of 10%-15%. Test drives clearly show faster acceleration, with 0-100 km/h times reduced by over half a second. However, pay attention to vehicle ECU version compatibility, as some newer CT5 models may have tighter parameter locks. After tuning, it's recommended to perform a basic inspection to ensure stable engine operation. There's not much risk—just a small investment for a performance boost, perfect for some daily fun.
