i did a home grind until i started making some money and bought the m&h #2 pin but my home grind was way smokier than this M2 pin i could only imagine what my egts were then. custom grinds are unpredictable so i'd stick to something that is "manufactured"

 

It all depend on;
Your other modifications,
How you drive,
How you use your truck.
Watch your EGT when you have a full load on. That will tell you.

 

It's taken me quite awhile to get my fuel cone where I want it. Every spring and fall for the past 4 years I pull it to inspect the guide pin track. Last week was the first time since I had the truck I did not do something, either grind & shape a little or take some more of the washer off. At one point a couple years ago I even used the welder to add some back in around the middle and lower portion of the profile. The guide pin will only go so far, and I considered getting full upward travel with minumum extension on the guide pin to reduce low boost smoke just as important as max travel at full boost.

I left a couple turns on the table with the full power screw, now getting 29psi at full boost with stock IC injectors and very little low boost smoke. You can't do that on one of these trucks without a properly designed fuel cone.
