Here is a graph that shows the affect that the rls Injection has on the intake air temperatures (IAT).
The red traces (solid and dashed) show the air temperature
before the intercooler. The blue traces (solid and dashed) show the air temperature
after the intercooler.
The dashed lines are without the rls Injection. The solid lines are with the rls Injection. The dashed lines (no rls Injection) have been overlaid onto the solid lines (with rls Injection).
The weather is 88 degrees F. Eight runs were made to 60 mph, in 2nd gear, before recording the runs that you see here.
As you can see, the rls Injection is taking another 10 to 30+ degrees out of the IAT.
