Just did the 6637 filter set up- turned out good.I also changed out the CPS while the truck was cool and in the driveway.Nothing was wrong with the CPS I swapped out, I was just playing it safe after reading up on the problems a bad one can cause. I'll keep the original for a spare. My truck is a 2001 with 75k on it.
LOL , another PMS addict,
on the other hand you should have left that cps in there, you never know what you put in there, just so you know, with electronics is like that IF aint broken dont fix it,
but on the other hand this does not apply here , on FTE is like this " if its not broken - fix it till it is" LOL this is somones Quote, not mine ,
I found this site in May of this year. The mods I had at the time was, muffler delete, superchip, and that was the "cats meow" around here. Oh I also had a K&N filter. I have seen the light. Planning on the next steps. So have fun with it and keep it safe.
