Hey just saw this on Facebook, good option for us that don’t live by tap out. Also nice to see some new vendors maybe moving into the space.

Also their website has a product listed:

JB4 for 2021+ Cadillac CT4, CT5, Turbo Including V and BW (BETA)

Power gains of up to 100hp and 120wtq to the wheels on a stock vehicle. This plug and play tuner attaches to two easy to access sensors in the engine bay and works with your factory ECU tuning to remap your boost, timing, and fueling for optimal performance and reduced turbo lag.

Seems like they haven't even gotten the car on the dyno yet, but encouraging nevertheless.

Yeah seems like it’s in beta but looks promising, their charts show alot of info including AFR/timing etc which is nice to know we can send in logs etc and dial in the tune

This is an exciting development for the Blackwing community! We look forward to working with Burger Motorsports to test, validate and calibrate their product.

Does the jb4 piggyback require the error code killer?

JB4 will clear codes on most platforms but it no longer auto clears codes.

This post kind of lumps the 4 and the 5 together, but for the LT4, what's the max boost that can be run with the waste gate fully closed? An extra 3-5 PSI is pretty significant.

This post only refers to turbocharged Blackwings. Supercharged ones wouldn't be able to have their boost increased via electronig piggyback controllers.

Maximum boost depends on several variables. One of the biggest limiting factors is fuel octane.
