so…
dont know if it helps alot but i feel it on butt dyno(probly mental too)
one thing is
that it makes the exhuast much much myuch louder,.
before msd driving inder 3k was stock with a tad of rom rooom
after msd 1-3k sounds much louder…
weird never knew msd would do that…
thats y my mx always sounds louder than others lol…
i thought it was b/c my small 10" resonator instead of the reg greddy one.
just posting up for peeps to share some thoughts of why it did that…
