I bought an M&H M2 fuel pin. M&H offers a variety of profiles the others do not. The one size fits all approach didn't fit my needs, neither did a ground stock pin. The M2 does exactly what I need it to do, so I'm happy.

The DennyT pin is my favorite because it is made out of hardened steel that won't gouge over time. The profile on it is very smooth and fluid compared to the other pins that have more of a "stepped" cut and I believe it has the deepest cut. That means that you get a very smooth adjustment in fuel rate as you push harder on the go button and you get more fuel overall due to the depth.

Make sense?


Here we go... There's two pins in this equation. The "adjusting pin" or fuel pin as everyone calls it and the "guide pin" that rides on the profile of the fuel pin. Your really only going to get as much fuel as the "guide pin" will allow. You can cut the so-called fuel pin as deep as you like but the "guide pin" is only so long and will travel down the fuel pin cut until that's it, and that's it...

All you guys running the denny t pin better look at them. I have been hearing they are grooving out some. I have way more fuel then I need with 6x16's and a stock fuel cone. :D

My truck is a working truck. Under normal driving condition (low boost) the M2 doesn't supply any more fuel than the stock pin on the shallow side. After about 18psi or so the notch deepens rapidly and allows more fuel for a jump in power. For heavier loads this works out great.
