I'm actually very happy with the performance of the kit. It doesn't reach max boost until redline but has about 3psi at 3k rpm. Power delivery is very linear, it just keeps building until redline. I don't know if I would trust the engine holding together if boost came on more suddenly. My car does eat MAF sensors and rear tires but gets average 26.1 mpg because I don't need very much right foot anymore.
