I have an m-max derestrictor in my hands and i was wandering to install it
or not...
I have done the wiresplice so it will be a messy job to do.
One friend told me that his mc21 goes 14000 with an m-max box and i
was jealous...Every dyno test ive seen power ends at about 11.200
so maybe he is an another liar...
Has anyone compared all the derestrictors on a dyno or something so we dont spend money for nothing?
Thanks
