Bri- Yes I definatly had lots of problems with this when I first got my motor together. I took it to several mechanics that couldnt figure it out, so I just went about it myself. Over time I finally got it to run pretty damn good.
Here was what I did.
First, bump your fuel pressure about 5-8psi, and I set my timing at 18. These helped. Then set your Idle to about 1100rpm. This isn't bad at all, and much better than stalling. After youve set the idle, get your TPS voltage set. If you dont know how, just ask on here, its not too hard. Make sure its set at .98V. Remember setting your idle will change your TPS voltage, so always do these together. Once you've got all that setup and its idling decently. Disconnect the computer for 30min so you can reset the computer.
Hook it up and let it idle for 5 min with no accessories on. After that take it out for a drive, and drive normal, then get on it some. over a day or two it should run pretty good. If not, you may need a custom chip burned. But I got a JMS chip and it didnt so **** for me.
