Steggy stage 4 mods ?

Hey fellas , so i ended up ordering a off-road X pipe , billet flow 2.76 with snub, JLT RAI, and colder plugs. My attentions where that was it. But now my buddy has a stage 4 steggy ported and polished stock Eaton with a accufab Tb and elbow. My question to you guys is if I bought the blower off of him what if any other supporting mods would I need for that ported beast on a 2.76 pulley ? Would I need a 4# lower on more fuel and bigger MaF or no?

The lower pulley isn't required. But it's a good way to go for a little more boost. My buddy has a stage 4 with the 2.76/4lb combo. It's a fun set up. He needed 60lb injectors and he's running a BA2400 MAF. His pumps were maxed last time I I datalogged it. But they're 160k mile pumps.

Right on appreciate it. From the research I found was a lot of divided opinions. Hoping if I pick up the blower all I’ll need is a MaF extender and a BAP since I’ll
Be running the stock
Lower.

Going with a larger lower will also get you additional torque.

Sure that will have to wait until
I can get more fuel fed to her. The ported blower isn’t a done deal but hoping I can pick it up !

IMHO skip the extender and get a different MAF. I've had both and prefer to tune with just the MAF.

My setup:
Steggy 4
3.1 upper
8# lower
40 amp bap
2400 maf
Stock injectors, stock pumps.
498hp/530tq

@apex svt, that 8 lb. lower really bumped the torque. Very common with larger lowers. What octane fuel do you use with your tune?

Yeah it’s got some good low end, makes it fun to drive. It was tuned on 93 pump gas.

I figured it was 93 octane.

My old ported Eaton made 504/494. I would have loved to have seen torque up around that 530 you're seeing. Torque is what we love on the street.

Go crazy and run it on e85. My old ported Eaton 2.93/6lb lower on ethanol made 552/575. That was a fun setup. Ran 10s at 132 with that little heaton
