In order to get accurate reading, you must have a grommet style IAT sensor in the proper air stream, standard screw in temp sensors are not as accurate (pickup all the heat from the engine and under hood) and most have different transfer functions. When your in this area with our twin screw, the temps very rarely change and gives almost zero tuning ability since there's almost no swing in temps. Thus, its not required to monitor post SC. The proper system, such as most factory system has an IAT 1 and IAT 2.
Most roots systems go 30-60deg F over ambient under boost, most twin screws are at least half this. Ours, with the oversized IC and SC design stays with 10degs of ambient up to 12psi when measured in the air stream.
Tunes will be the same, no need to "re-tune". Especially if our IAT table is used as the baseline.
Can't compare a GT500 app to the Camaro app. Most GT500's run very high boost with very tight bend deep manifolds which adds heat.
