Default LS1 dyno fuel curves

I dynoed my car the other day and did not get the results I was hoping for. I added a predator to my car as the only change and only picked up 4hp. I went from 332hp/355tq to 336hp/355tq. I even played with the tuner some. I got like 3 more hp from putting the poly ends back on my MAF. I ended up at 339hp/356tq for the day. The thing that got me was the A/F curve. It was like 16 to 1 from 1500rpm to 4500rpm, then it goes to 13.2 to 1 until redline. The guy running the dyno said that most of the LS1's he has dynoed test like this. I have know the guy for some years now and know he runs a very reputable shop. I called predator and they want me to upload them my custom tune they made for me and the dyno chart to see if they can adjust it some if needed. The cars feels alot stronger since I put the custom tune in it (at least on the butt dyno.) but it did not show up on the dyno. My question is how does everyone elses dyno chart read in comparision on thier A/F ratio? Thanks for the help.
