Vince dropped by with his 2023 CT4-V Blackwing for the Purple Belt treatment. Since his car had the A10 transmission, we worked with HP Tuners to unlock and tune both the ECM and TCM. We provided Vince with two custom tunes. The first is his ‘daily’ tune, which constantly reads alcohol content and automatically scales fueling and ignition timing, producing 516 whp on 93-octane pump gas and 571 whp on E60 or higher. The second is his ‘kill tune’, which has boost and timing both cranked up. This tune produces a peak of 614 whp.
