The Bullydog went in a friends stock 2wd. Boost went from 16 to 20 with no other mods. 3200 spring will go in soon. DennyT's went in my crewcab. Wont test until I finish my inframe. Waiting on one set of rings from Cummins.

The nice thing about the BD "profile" (and I'm not talking about anybody's piece, generally speaking - you can whittle up a piece of metal with a lathe and grinder any way you like) is it holds full fuel back until towards higher throttle and higher boost levels - when you really need and want it.

But if you want drive around blowing smoke all the time and wasting fuel, by all means get the more agressive profiled pins!

Also unlikely to cause the commonly encountered fuel pin leak when the fuel pin extends out beyond it's useful travel into a deeply cut cone.

The M3 from M&H is teh same way, holds teh fuel out till the very end. But it goes as deep as teh DennyT som you still have teh fuel leak. Mine has leaked since the 1st day I had my DennyT, not givin me any real problems though.
