Steve from Texas brought his ultra cool blue M6 2023 CT4-V Blackwing in for Blue Belt upgrades and some carbon fiber parts he wasn’t able to get from Cadillac. We used the Tapout Tuning Module (TTM) and did a custom dyno tune, producing five different power levels that can be switched in seconds using the no charge cell phone app.
P1 = 440 whp
P2 = 470 whp
P3 = 492 whp
P4 = 512 whp
P5, P6 and P7 = 527 whp
We spent the last several months working with HP Tuners to figure out E01 tuning. As it turns out, a new torque model concept is used in this controller, which is very complex, and at this time there is no means to properly generate new model data for it. However, we were eventually able to find a solution around this obstacle. This was the most challenging tune we have ever done. Dozens of new VCM Editor tables needed to be defined, and many new VCM Scanner PIDs were added as well.
All the extra time and effort proved to be worthwhile. We picked up more than 40 whp and 50 wtq throughout most of the powerband. Then we had Brian from Brut4l Ass Kicking calculate the optimal shift points so we could program the TCM accordingly. 0 to 60 times have now improved from 4.8 to 3.8 seconds, making this car launch as hard as a CT4-V Blackwing! These numbers were all on 91-octane fuel with no mods. There should be even more gains with 93-octane. So, whether you’re looking to Remote Tune your CT4-V with HP Tuners or bring it straight to our shop, we’ve got you covered!

Franz from Maryland dropped his 2016 M6 ATS-V off for an upgrade from Purple to Brown Belt. This is a low mileage car and it drives like new. Amazingly, it also makes 737 whp now on E60 fuel!
Josh from Pennsylvania brought his beautiful 2023 CT5-V Blackwing in for upgrades. We installed all the most common mods including larger throttle body, ported stock supercharger, camshaft package, auxiliary fuel pump, flex fuel kit and header system. Josh’s final calibration is a fully automatic flex fuel tune that will work fine on any fuel from 93-octane E0 to E85. It starts adding WOT ignition timing when ethanol content reaches E20, and hits full power by E60. So E60 to E85 will make the same power. Here are the results:
All the above numbers are using SAE correction, so you can add ~ 2% if you want to see STD numbers.
Dave dropped off his sweet M6 2023 CT4-V Blackwing with a wicked cool metallic forest green wrap for our White Belt Package plus a Gigs ported throttle body with the JB4 tuner. He was interested in seeing the kind of gains the JB4 could produce, so before installing any modifications, we strapped Dave’s car to the dyno to see what kind of power his car was putting down. To our surprise, this CT4-V Blackwing baselined as one of the highest we’ve seen; making 432 whp.
After installing colder Brisk spark plugs, Gigs ported throttle body and the JB4 tuner, Dave’s car produced a respectable 488 whp! Those are some impressive gains for a few bolt-ons!
