modding help needed

[01LS6ws6]

i just got an 01 ws6. the mods were all done by the previous owner. this is exactly what he told me he had done:

ls6 crate motor, upgraded 6spd trany w/ pro 5.0 shifter, professionaly tuned, slp mass air, 42lb flowmatched injectors, underdrive pulley, slp longtube headers, suspension, adjustable slp torq arm, lower control arms, fidanza flywheel.

2 questions:
1.) how much do you think these make at the wheels?
2.) what should i do next?

i am in college and on a part time job budget w/ the car payments but still, this is my pride and joy [other than the girlfriend but shh] so i would like to put some money into this and keep it around for a couple years, while going fast during those years. my thoughts were maybe just going with an STS system from a cerrain website where they give you all fuel and other things needed for it or go with the ms4, a couple bolt ons and some DRs [maybe some nitrous for the track or smoking some ponies]. my goal would be right around 500rwhp n/a or if i go STS, well we will just see how much boost i feel liek running.

any help is appreciated!!

That STS is miserable behind an M6. You will make 1-2 psi in first and 3-5 in second gear, and FINALLY get to full boost by third. They work ok on a stalled auto... More of what I'm saying can be found in this thread and the thread that I linked within it http://www.ls1.com/forums/showthread.php?t=74062

with 42lb injectors in there, the previous owner must have either used dry nitrous or some form of FI, they are HUGE for the mods that you have right now.

thats what i was kinda thinking. how big of a shot you think i could run on that? my friend is an f-body freak and he says taht i could go as far as a 250 shot but idk. id be a little weary about that.

I sure wouldn't... do some reading around the forums before you drop your coin, there is a lot of info (and some misinfo out there)
