I have GIAC flash loaded, 3800cc injectors, DV, drop in K&N filter, K04-15

 

DUDE! 3.8L injectors... MY GOD MAN do you have a trailer with fuel pulling behind you?!? Just kidding, I know you meant 380cc, but I had to have fun with that! I too wanted to do this as well, but the general consensus on this mod is that it isn't worth the trouble or potential damage this could cause if the engine isn't properly balanced, but I'm still on the fence over all this personally. If you do try it let me know what you thought of it; I can't see neuspeed making something that would actually harm your car as they could be someone liable... Just my .02$

Unless you are tracking your car and are looking to knock off 0.1 second, it probably isn't worth the money.
You seem to have all the right stuff, but you don't mention an exhaust.

 

Underdrive pulleys make a difference on V8's... freeing up like 10 - 12 hp sometimes, and if you rev the hell out of your car, the pulleys are pretty good, as your accessories spin slower.

 

i wouldnt get it
damn i need my 380cc injectors and revo

 

Get on that **** Panda!

 

^^^He never will. Btw- i would not install pullies on a a4, there are reasons there not that popular.

 

and those reasons being... ?

 

unless your looking to knock miliseconds off of your quarter or lap times, not worth it, bad investment for street driving, as your ac and accesories dont work as well...

 

Reasons being they can be loud,ever listened to modded 1.8t at idle with them? With ac they almost chatter like a lwfw at times. Just my .02.
