I tried the Weber on a carbed 22re, tried everything all the tip tricks, reset everything a couple times. Never did get it to run decent, it would load up bad over 5000ft which is where I wheeled most of the time. And living at 750Ft elev. it was tough to tune for both. I didn't have the stock option since the truck was dead when I bought it.
So I recommend no Weber stay stock, then swap in an RZ when you can.
