2023 CADILLAC CT4-V BLACKWING 608 WHP TWIN TURBOCHARGED

Steven from Ohio decided to upgrade from Blue to Purple Belt now that we have HP Tuners access to the Global B ECMs. The results speak for themselves. He doesn’t just hit his peak power number for 50 or 100 rpm. Instead, his car now carries 600 plus whp all the way from 5,200 to 5,900 rpm. No other tuning company come close to the LF4 knowledge and experience of Tapout, and that’s why our powerbands are simply the best.
