I asked Grok about the risks of running the JB4 and here is what it said.
Anybody disagree with this info?
There isn’t a centralized database of "damage complaints" specifically tied to using the JB4 with the Kia Stinger, but I can piece together what’s commonly reported from user experiences, forums, and discussions to give you a clear picture. The JB4, a popular piggyback tuner from Burger Motorsports, boosts performance by adjusting boost, timing, and fueling, claiming gains up to 100 hp and 100 tq on a stock Stinger. While many users rave about the power increase, some have encountered issues that could lead to damage or complaints. Here’s what stands out:
One recurring issue is misfires, often linked to spark plugs not keeping up with the increased boost. Stock plugs can crack or fail under the added strain, especially on higher maps (e.g., Map 2 or above). Users frequently recommend swapping to colder plugs like HKS M45IL or Denso, gapped to around 0.022-0.024 inches, to mitigate this. For example, a Stinger owner reported rough running and a check engine light within 24 hours of JB4 installation, later traced to a loose intake air sensor connection, not necessarily damage but a sign of install-related hiccups. Another case involved a 2019 Stinger GTS where misfires persisted post-install, leading to a dealership flagging combustion issues in cylinder #5—though it’s unclear if the JB4 directly caused it or if shoddy installation/coil replacement was to blame. The owner faced a potential engine replacement, with neither Kia nor the installer covering it.
Boost leaks or overboosting are other concerns. Without proper setup—like ensuring Electronic Wastegate (EWG) connectors are used on modified setups—boost can spike or drop, stressing turbos or triggering limp mode. A user with a heavily modded Stinger (downpipes, intercooler, etc.) noted the JB4 cutting out during gear shifts, with AFR dropping dangerously low (e.g., 10), suggesting a tuning mismatch or hardware limit. While the JB4 has safety features to revert to Map 0 if it detects anomalies, prolonged stress could theoretically wear turbos or internals faster, though no hard data confirms widespread failures.
Warranty disputes also crop up. The JB4 is removable and leaves no ECU trace, but if damage occurs (say, a blown engine), dealers might deny claims if they suspect tuning, especially with visible aftermarket parts or logged boost levels exceeding stock (around 12 psi). A technician on a forum noted they’d blame a JB4 for driveline issues if boost logs showed tampering, even if removed before service.
On the flip side, many run the JB4 trouble-free for years, especially on conservative settings (Map 1 or 2 with 93 octane). Long-term reviews on Stinger forums suggest it’s reliable when paired with basic mods (intakes, plugs) and proper maintenance. Complaints often tie back to user error—poor installation, skipping plug upgrades, or pushing high maps without supporting mods—rather than the JB4 itself being inherently damaging.
So, damage isn’t guaranteed, but risks exist: misfires from inadequate plugs, potential turbo strain from overboosting, and warranty headaches if caught. No definitive stats show how many Stingers have been wrecked by it, but the louder complaints tend to come from aggressive tuners or sloppy installs. If you’re considering it, stick to lower maps, upgrade plugs, and double-check connections to keep trouble at bay. Anything specific you’re worried about with your setup?
