Your Gen5 Camaro ZL1's stock intercooler system is insufficient. The stock setup comes with a tiny amount of fluid and when you are doing pulls that tiny amount simply isn't enough to absorb and reject heat. When your intake air temperature (IAT) reaches 140 degrees or so your ECU starts pulling timing (power) from your setup. XtremeCFM's ZL1 engine bay
