you're going to need a port job on your heads to match the LT1 heads with the LT4 intake.
You won't need injectors, stock 24lbers will be fine. As for a tune, Bryan Herter @ PCMforless has a great mail-order tune for hotcam cars. Check out their website at www.pcmforless.com. Don't waste money on a worthless tuner like an HPP3.
You're probably already aware of htis, but make sure you're running a full exhaust on your car so that you don't choke the hell out of the motor running that cam.
Another suggestion I'd make is to go with a torque converter first if your car is an automatic.
Actually, just post a list of the mods you already ahve... I should have asked for that first

LT4 intake is not an upgrade, it just has more material so it can be PORTED to match LT4 heads it does not as cast. If you meant heads and intake there are cheaper ways to get more flow than stock LT4 stuff, like just porting the heads you have now. CAI is a very good thing, DO NOT screw with the MAF it is not a restriction until you get very deep into stroker territory all a different housing of aftermarket MAF will do it screwup your tuning. Underdrive pullies are about a waste too best thing they do for an LT1 is slow the accesories to prolong their life and keep PS fluid cooler those are not concerns unless you autoX or the like and they would see sustained high rpm use. Other vehicles see better gains from pluuies because they have belt driven waterpumps and reducing the speed of the accessoried plus the pump can reduce parasitic losses enough to be worthwhile.
I would suggest you do a lot more reading before you start buying parts.

IMO you should totally forget about a cam swap until you can let it breathe properly. I would have a full exhaust before I even thought about a cam swap- and definitely a torque converter in an A4.
dont waste money!
im sure your motor has some miles on it ,go ahead and freshen it up and have your heads and intake worked,add the cam and youll be a whole lot safer
but first id stock up on bolt-ons
