Trying to sort out a lean idle

Ok, kinda new to this. I'll start out with what I have. 383, Stealthram, 30lbs Ford injectors, running the APYP bin. Right now I have the injector constant set to 33, with this it idles rather lean, but at cruise it runs rich. Rich is BLM's around 113-115 and lean is BLM's around 145-150. If it's sitting still and I just crack the throttle it is almost 128/128. Last night I read through the archives and read a few posts telling to go into the MAF1 table and try adjusting the GM/S up some to try and richen the idle. So I went in and moved everything up about 15% which is what I figured I was lean by. Installed the chip and drove it some today, runs somewhat better but the changes weren't what I was expecting.
So did I do the right thing and just need to keep going, or do I need to backtrack and change something else? Can someone point me in the proper direction? Thanks in advance guys!
