Just bought a P1SC Head Unit !!! Just bought a P1SC Head Unit for $1,250. 
Should be here some time next week. I have a deal lined up to buy an original style kit for $980, minus a few parts.
I will need to buy separately:
-injectors (42lb/hr for $289)
-pulley & belt (?)
-fuel pump (?)
-new valve springs (?)
-gauges (?)
-air pump relocation bracket (?)
I plan on running around 450rwhp to start with this year. Any suggestions on pulley size and where to buy? I currently have somewhere around 305-315rwhp.
I will be running street tires, transmission cooler, stock 2.73 gears, stock torque converter in an attempt to spare the a4 transmission.
My only concern is the air pump relocation bracket. ProCharger is notorious in the corvette community for crap customer service, so I'm wondering if I'll have difficulty getting just that part from them.
Also, for running 6 or 7psi, what gauges do I absolutely have to have?
What springs should I run, LS6 or Comp 918?
Damn I'm exited! One step closer to forced induction!

The Comp 918 springs or the Patriot Gold springs would be what I would recommend.
Gauges aren't essential, but I do recommend a fuel pressure and a boost gauge. The fuel pressure gauge will allow you to monitor the fuel pressure, to make sure the fuel pump stays healthy. A fuel pump that is going bad will drop pressure, which would lean out the air/fuel. The boost gauge will allow you to make sure the blower belt is not slipping. Once the blower is installed, the extra power will seem like more than you will ever need, but it is normal to get use to it, then you'll start to wonder if you're making as much boost as you once did. The boost gauge will ensure that all is well.
Was the head unit on a Corvette?
Did you purchase the head unit mounting assembly, along with the idler pulley, etc?
Did you also purchase the complete intercooler assembly?
Is this a six rib kit, or the 8 rib? Since it is the P-1SC, I am assuming it is the six rib.
Did you get the bypass valve?

While your at it just throw a cam in because if you plan on running 6 or 7 psi I strongly recomend pinning the crank shaft. And for that your gonna be moving steering rack to access the crank bolt might want to consider oil pump depending on how well your pressure is now, being your gonna make that much power think atleast LS6 timing chain. I would recomend stonger timing chain, rather than springs. This is all considering its going into your vette.
3.70 gave me 7psi
3.85 gave me 6psi
only other mod was LG Headers
I went back to the 3.85 I was sweating the stock bottom end on stock internals.

The bracket will be included in the original style kit I am looking at buying, but not the pulley. I will have to buy that separately.
The intercoolers and piping will be included.
Six rib
Not sure about bypass valve, I'll have to ask the guy I am buying the kit from.
Are there any other important parts I need to ask about? The person I am buying the kit from is keeping the air pump relocation bracket, what else besides this and the bypass valve should I ask about?
Also, can you quote and p.m. me a price on a new tuner kit(no injectors or tuning) minus the head unit? I might need to go this route if too many parts will be missing from the original style kit I am looking at buying.
Thanks!

I'd do 918's, some pushrods and a Racetronix Fuel pump. Also, if you ditch the AIR pump, then you wont need relocation brackets. Not sure if emissions are a concern. Gauges are recommended. Belt is about $30 and the Pulley is about $80. Belt length depends on the pulley used. I would definitely pin the crank.
The cam would be an easy swap being there. Just depends on what you want. 2.73's suck, but you can run them..
450rwhp should be no problem with what you are looking at.
LAST BUT NOT LEAST!!! A PCM TUNE WILL BE REQUIRED!!! You can't just bolt it on and go. It will have to be tuned. ~$450
I saw that kit for sale, it was a good deal.
I'll be fun once you get it installed....

What's really sad is that there is probably someone out there who has actually tried to run FI on the stock tune.I was leaning toward 918, but may go the double route in case I ever have the cam changed. I like the looks of the Thunder Blower Cam.
THANK YOU for the clarification on the air pump. I wasn't sure if it was just some emissions garbage or an important part. Emissions are not a concern here in FL.
ECS carries the crank pinning kit for $70, I'll go that route unless anyone knows of a better deal.
2.73 do suck for racing, but my plan is to keep modding the car over the next few years and eventually get a built tranny and a built 3.15 or 3.42, depending on power.
I may not buy the used kit, depending on the price I am quoted for a new tuner kit minus the head unit. $980 is a heck of a deal, but the guy keeps coming up with things he needs to keep. First pulley, then air pump relocation, what's next? Something I'll absolutely need and couldn't source elsewhere? Only time will tell...
Thanks for the input!!!

I was thinking that 450rwhp is the most I should shoot for with the stock transmission, but is hp the real culprit in killing the A4? Or is it high rpm shifting, excess heat from tq converters, launch traction, etc. ???
Could I go higher than 450rwhp and still be reasonably safe running street tires/2.73 gears/stock torque converter? Also, centri's power comes on later, would that also allow me to get away with running more boost?
Geez... I swore this would finally make me happy, but I havent even changed the car and I'm already itching for even more.

About drivetrain, I'm not too familiar on the A4 C5's, but have dealt plenty with M6's. With ~450 N/A hp, I broke a clutch and the torque tube. From what I hear, the A4's weakest link is the trans. The cooler should help you out. Also mileage is a concern. The newer the car and the lower the mileage, it "should" last longer. There's guys putting that power down on stock a stock trans.... so it is hard to say for certain.
Buddy of mine toasted his A4 in his Camaro (4L60E same basic trans) with juice. 450rwhp car. But it had lots of miles and beating on it. Went with a new RPM trans and a 3500 stall.
I really think you would be much happier with an ATI ProCharger D-1SC eight rib kit, since judging from your signature you seem to be like the majority of us, always looking for more power... The extra belt width really helps with belt slippage.
