Cadillac tuning at Rapid Racing
We support 80 Cadillac vehicles across 19 models, covering model years 1999+, through AutoTuner and HP Tuners. That includes diesel, gasoline powertrains and 14 engine and transmission controllers.
Each Cadillac tune is calibrated for your exact hardware and fuel, then verified with real data on our Dynojet 424xLC2 in Jenison, MI, serving Grand Rapids and West Michigan. 13 of these Cadillac applications also support remote tuning, so you can flash and datalog from anywhere. Not sure which controller you have? Browse all supported ECUs or ask us.
