Hello Guys. first I'm a nuts and bolts guy and tuning is completely new to me so please forgive my ignorance.
My truck is a 93 Blazer 5.7,

Edelbrock 7116 intake
Headers 2.5 dual exhaust

I got the AutoProm and tunerpro rt. Im learning alot playing around with it and reading the forums but its like learning chinese. Right now im dumping so much fuel that i drown out at idle. Im looking for a Bin that will get me a better starting point than stock. my neighbors already hate me and someone filed a noise complaint on me yesterday LOL.
any help or advice is appreciated

If you've altered fuel pressure, you will need to adjust "Injector Flow Rate" in TunerPro before you can do any tuning. You can find it with "Parameter Finder" in TunerPro. To find it in TunerPro, press Control+F or it can be found under the "Tools" tab.

Here is a simple fuel flow calculator to help get you in the ballpark.
