Very impressed with the efforts that HP Tuners has ramped up to finally get the CORE ECU into a formidable beast in the standalone market. Those that have a lot of time invested into using VCM Suite for OEM calibration work will find the navigation very familiar. Currently working on a integration harness to use the CORE with a factory E38 or E67 controller to not kill other OEM functions of a production vehicle.

Can't argue when the math lines up with a validation. This is a 2022 C8 with a 416 cubic inch motor I had built "all motor". Airflow was up 14 gr/sec at 4000 rpms and 30-44 gr/sec at 5500-6400 rpms after swapping from a aftermarket aluminum intake to the Performance Design Carbon PTr intake. These same results I have duplicated numerous times in the same areas which surely indicates areas where airflow is stalling. Great job Caleb Newman for truly understanding airflow tuning vs just machining. Upcoming tech article dropping soon at LSX Magazine on a deep dive into intake manifold designs.
