edit: after that its just that the headunit is to small to hit 650hp on the air hungry vhr

2. The stillen manifold/intercooler setup is not efficient enough and there are power gains by switching to a front mount because of the cooler iat
3. The piping after the supercharger with the mafs in it is under sized and delivers different amounts of air to both sensors, because of the smaller diameter it also will max out the maf sensors range bellow 500 hp so your car wont know how much air its getting past that
4. Because of the sharp bends it has to make the intake coupler is a significant airflow restrictor
