I'm gonna say, not really my shee hasn't dropped off any power or shit and get.
I have became used to it, and I'm just gonna guess thats all it is with the blaster too,
Its just like car speakers, sure when you get them they are loud as hell but about about 3-5 months, they don't seem loud anymore. kinda the same thing with mods.
or maybe it needs to be adjusted on. Gotta remember any and everything can feel like it's crappy if its not set up just right.
hope that helps
Also remember that your front tires spinning will help keep your front end up, so starting from a dead stop is harder then a rolling start. (in my opinion)
