emissions cam I'm researching a sniffer friendly heads/cam setup.
I know the TR224/114 or 224R/114 cams will pass easily.
I talked to two local tuners about something a bit bigger.
Both recommended a 228/232 115LSA custom cam.
My end goal is a 401+ rwhp car that is daily drivable and sniffer
friendly.
I also am upgrading to a built A4 with a mild stall, 3000 or 3200.
Is the 228/232/115 cam more worthwhile than the 224 cams?
What heads would be a good match? 5.3s or LS6s?

Most states are moving to a non-sniffer test based on PCM codes. These are much easier to pass than a sniffer.
Anyway, I have a very small cam and ALWAYS had a hard time passing the sniffer in NY - even with a tune. At one point, these jokers even retroactively applied stiffer sniffers tests for older cars!!!!! That should not have been lawful but they did this anyway.
If I had to deal with a sniffer test, I would wait until the state went to PCM testing!
Good luck!

There are ways around it but then it'll have to be some under the table kinda deal.

With a decent set of heads and the TR224 you can crack 400 with a good tune easily. Figure that would be ok with CA emissions. It really depends on what compression your looking for inbetween the 5.3 and LS6 heads. They both flow similar #'s.
