Can I run a 110 or 112 Lsa on an A4? do I have to get a torque Converter?

 

Yes and yes,you can run a 112or 110 LSA on a A4 with a good tune,and yes you will definately need a vertor,i drove mine around with my 114lsa for about a month before i got my vertor,it sucked.

 

How do you like that cam?

 

I love the 224,drives and idles pretty much like stock,you cant even tell its there,unless you know what you listening for.I gained 35rwhp for the cam and ls6 intake,it peaks at around 6200

 

fwiw i wouldnt do a 110lsa 112 with an auto is about as low as I would go...my car drives very well around town but yah i would recommend a converter before a cam in any instance...they are the same up front price if you consider you'll need springs with a cam but will give you twice the gain overall.

 

I had a tr230 on a 111 and it was fine with my a4. I currently have a 112+4 lsa

All you need is a good tuner and you should do the tq converter before the cam.
You will get more performance from a good converter than you will from a cam.
