Need Modding Help L67

I need a little advice and direction where to go from here. I have a stock GTP has aprox 84k on the clock. Currently running AL 606's with Belden wires. I have a lot of competition around here and I need to be able to crush these cumstangs and rice burners.
I am pretty certain on these mods in the very near future tell me what you think.

ZZP 3" CAT w/Cat

ZZP Cold air intake 4" cone

Overkill Can tune

MPS (unsure what size)

AL 105's

Right now im getting a peak of 5KR and im pushing about 7psi at about 4k RPM I want to be in the high 12's or low 13's in the quarter mile. I'm sure someone is going to tell me headers but I would like to save that for last after the above mods if I still have knock. My main question is will I still have KR? I plan on waiting to pulley swap till I am under 2kr.

What would you guys do?
 


Skip the cat back, its pointless and a waste of money. Get a 3" dp and a front plog at the least if you don't want to run headers. Make your own intake its cheaper and just as effective. With the dp plog Al105s and a tune you should be able to run a 3.5 pulley pretty easy, you might be able to drop to a 3.4 but its hard to tell as every car is different.
 


Yeah I've read of some people stock hitting 6*. Each engine is different, my Silver car before the engine took a dump saw 4* of KR.
 
Is this a 13 second setup? and the reason I felt I should go with the ZZP CIA was because of heat. Isnt it true Pulling cold air in + S/C = more boost? What is the first Mod I should do? I was thinking the CIA or Downpipe?
 
And the cai does nothing for our cars since the blower on it is a super heater it all becomes the same temp no gain really

You are not going to get into 13s with just a pulley and a cold air intake. Sure you could run a small pulley a custom tune and race gas like Twinv6, but thats not an everyday driver. A 13 second every day driver you would probably need a cam but I could be wrong.
No a cold air induction on these cars does absolutly dick. http://www.grandprixforums.net/dyno-science-cai-box-vs-open-cone-intake-33225.html Make your own just search homemade intake or diy intake.
 


right now zzp is out of plogs. And for the dp since its a l67 you should get a 3 inch dp catted will be about 50 bucks more
