The stock intercooler is inefficient and inadequate for higher than stock boost levels. Want free power? Bolt on an efficient intercooler.
Steet intercoolers and track intercoolers are not optimally designed the same. A steet intercooler must not only cool the intake charge but battle an issue that kills power and causes detonation - heat soak. Stop and go traffic and long periods at idle are a huge issue with a street car.
The 3DLZ is 30 year old technology. The K27-xxxx series turbochargers are well documented as producing less heat and more power with a lower boost threshold.
