I did the same shortly afterwards. In fact you were the inspiration. The 3.25" pulley made 10 psi boost. My maggie came with the 42 lb. marine injectors, and they were fine, but at their limits (about 85% duty cycle IIRC). The stock maggie tune was pretty much OK as well. I only had to tweak the power enrichment cut-in to avoid a lean spot where I would have 1-2 psi boost but still stoich AFR. BTW, still have the maggie (almost 6 years now) and it still runs great.
EDIT: Should mention, this was for a regular truck with an aftermarket maggie kit, not a Joe Gibbs truck.

i believe his trans will be fine. there's a RCSB guy beatin on his with an 8.1 & still running strong (even after the abuse from his 454). i even talked to a guy from JGP a few weeks ago & he said they never had any problems with the transmissions with the power they were making

but it still stinks for me because before i learned what all this trans could take, i decided against the 6.0 so i would keep my trans 'safe'
now that the new's wore off, i'm starting to wish i'd've gone 6.0

true that!
heck... even the 3/4ton dodges used the same NV3500 (just with the s10 gearing & obviously the dodge bellhousing/input/output shafts)
what i thought was funny was that the LD2500s got the regular nv3500 while the 4.7 dakotas got the nv3500HD (a little higher torque rating & different gears)
