Will a Spyder Madd man Spring kit work with my Piranha GTI Eforce? Need to get something it came with the highest spring and it is WAY too hot for playing indoor locally

pmi springs and spyder main springs both fit and are the same lenth.

The hammer springs in the Spyder kit will work fine, but I THINK the valve spring is going to be different.

also using a reg to turn down the psi going into the marker will help you get to the lower field fps.
