Treatland recently started selling a new "high perfomance" reed block for the M48.
I got it expecting a little more speed? Acceleration? After installing I cant break 30mph, before installing I was getting a little over 30mph top speed. I have a 13. 13 sha currently w 72 jet and a MLM circuit pipe. Why would i be loosing a little on my speed?
Haven't spent much time with it but does seem to have a little more pick up than before.
