Hello I am owner of a GS/SM5
i have a k&n drop filter and just installed an hmf.
I had much warning from the numerous posts about the popping , sputtering backfire
I didn't realize how hard it was going to be too get an o2 mod, evoluzine went out of business
Ivanlee (Jim) messaged me and had an extra!
this forum and Jim are awesome
People like you are what driving spyders are all about
By the way I never knew my spyder could be unleashed with such fury
If stock was 0-60 in 4.6
what would y'all call out now with the o2 mod, exhaust, and filter?
any Owners have any numbers?
