LML SPADE & Smart EGT Control:
Exhaust Gas Temperatures (EGTs) give you an insight as to how much stress you are putting your engine under. It is the most accurate way to monitor if your current activity is safe for the engine.
In a factory tuned truck high EGTs would most commonly be a sign of a physical problem like a boost leak. However, a tuner added to an aggressive driver could result in EGTs beyond the desired limit.
Most examples of this also include a mismatch of your tune level and truck operation. Such as the guy towing in his race tune.
The LML SPADE by DuramaxTuner.com now includes a Smart EGT Control feature.
