Hey anyone who wants to help please respond.
I do not have any dynos near me, what do you think my rear wheel HP is?
Here are the mods on my 2001 Lightning

JLP Diablo chip (dual program)
JLP 4lb lower
ASP 2lb upper
JLP air intake
JLP powercooler
Accufab single blade
NGKBR7's
Boost bypass
Basanni Cat backs
160 stat
electric fan
Cobra R pump
Factory Tech valve body
NOS 80 HP nitrous kit

 

diablo is the devil's chip, so i'll go with 666hp

 

402 without the go-go juice...

 

Well, I know someone with almost the same mods, (minus nitrous) with a 6lb'er instead of your 2lb'er and 4lb'er, his was in the range of 420HP at the rear wheels. Now, one other thing to consider... is that when you put the 2lb'er on originally, you increased the crank to blower raito, so, effectively, your 4lb'er could actually make it seem more like a 5.... so, I'd guess you're running between 6 and 7lbs of extra boost. ANYWAY... so... my guess is:

420HP w/o nitrous
500HP w/ the claimed 80 shot..
