    I got an HPX from Riffraff Diesel to try and smooth out my injectors. I used an AE tool to check ICP and PERDELS. ICP looked fine, but PERDELS was a little high on most injectors, but well within normal range.

    Immediately I noticed improvement in my idle after installing my HPX. Check out the graph I have included. The graph shows my ICP at idle before and after the HPX was installed.
