I saw that before but I got to say I noticed no difference in sound. I did the fitting at the same time as my lift pump, at the time truck was running an Edge Juice it was falling on its face. I did both the fuel rail fitting the CP-3 inlet fitting and lift pump at the same time. The truck stopped falling on its face. I realize that these results are skewed by the addition of the lift pump but it is a very inexpensive mod. For what it's worth I am not sorry I did it and will swap the the old fitting from the driver side to the passenger side some day.
Yes they are a little skewed with no dyno or driving logs...
When you find the some day I still have a downpipe, DSP5 switch and tunes, buy a license for my spare ECM and tune it, purchase and install a lift pump, have to replace the rattly year old muffler, install the Mike L. springs, (scared of valvebodies, haven't opened one in 20 years) switch to Transynd yet to do, wanna help.....some day.....
You can do it Mike.
BTW you need the Trans-go kit to go with them springs. Just in case you didn't know.
One thing at a time.
I struggle to, my ambition seems to have left me.
