First question: why a goal of 400 fps?
Second question: is the cylinder matched to your barrel lenght?
Thrid question: what barrel was installed?

Imo you're spending a whole lot for not mutch gain. Higher fps does NOT equal greater range or accuracy. After 10 yeas tweaking guns my favorite setup goes something like this:

Tabio koba twist tight bore barrel
Metal bushings
Promotheus m100 spring
.25 quality bbs

Period. Give you a nice constant 330 fps low stress on the gearbox, battery life, gears and piston. The range and accuarcy is on par with any other gun I've owned that had shot around 400. When the piston and gears finaly give way ( 3-4 seasons down the road) replace with systema piston and high torque gears.

For battery I'm still old school ni/cads but apparently the lipos are turning out ok.

For upgrade parts I only recommend systema and promotheus. The rest well I'va had good and shitty from everyone else but alvays the same quality over a long while wih these two.
