My dad has a denny pin and it doesn't seem to have the gain that the bd pin gives, because his truck has more of a flooded feeling than the bd pin. WOT full blown to the wood after spooled feeling is exactly the same. His truck is stock in the pump department besides pin.
Point I'm making is the bd pin seems to be less aggressive with the same full fueling and it provides less smoke and faster spooling, the denny pin stage 1 or 2 seems to be more of a young kid smokey style pin.
I never ran a bd pin but I do agree I almost have to run a valve spring under the starwheel to control smoke with my Denny t stage II
I would not want an afc delete with my setup. My injectors flow all the fuel I can use so the afc is all I got to control smoke!
A tight afc will build far more power than flooding out your engine and drowning your turbo. I would bet on it.
With stock injectors, A heavy fueling pin, Or the pump top delete, would be a good performance upgrade, but If you want more... Then injectors is where I'd lay down my cash... then work on stopping 'em.
OR AD MORE AIR!
With fuel projected to go past $5 a gallon this summer I'd work on making the most power with as little black coming out the tail pipe as possible.
