Upper and lower pulley supporting mods???

I'm considering installing a 4lb lower on my ported eaton with a 2.93 pulley. What supporting mods do I need?

Dyon-tune (Xc2 or predator), upgraded MAF (2400BA or MAFia) 60lb fuel inj, bap, intake, exhaust, BF IRS diff. cover Brace.

What do you have already? For sure a BAP, BA2400 or MAFia, and more then likely 60lb injectors if you are at or close to sea level. bigger alt pulley as well.

3.2 alternator pulley to be exact...call Lethal for that.

The mods are as follows:

Magnaflow Catback
Sambandits old Ported eaton with 2.93 pulley
Diablo
A cheesy Densecharger CAI
IRS diff brace

I have the following parts sitting on the shelf:
4lb lower
BAP

I'm very close to sea level; approximately 250 ft above.

Then I would recommend 60lb inj, MAFia, alt pulley, and an aftermarket midpipe of your choice.

i did the 3.2 alt. pulley and fried the alt. went with 3.7 alt. pulley. spin your alt. shaft faster than 16,000rpm and its gonna go out
check this thread out for pulley ratios, i currently have the #4lower w/2.9 w/7000rpm redline on motor.
