To get the most out of your new turbo have it live mapped!!! and i would go for a 044 pump and uprated wiring

As for greens u will struggle to get anywhere near 400 bhp go for light blues or greys or poss 1000cc injectors depending on if u have any head work and cams (A must if u want more than 410 ish bhp)

This can be a costly conversion due to the box being the weak link after around 350 bhp

Driveability will depend on how its mapped
