Hi I am new to the whole tuning thing so bare with me. I have tunerpro rt and the moats burner with the g2 adaptor and I just put a 400sbc in it and I want to tune my TBI. Its not a stock one. Its been bored out to flow somewhere around 830 cfm. Trying to fix one problem at a time. The problem I can't figure out is that when I mash the gas pedal to the floor its accelerates "okayish" but then as I slowly let off the throttle it accelerates harder then at wot. What do I need to adjust. I am guessing its a fuel issue and a TPS issue. Any thought or ideas what to change in tunerpro would be great bec I don't know what half of the tables in tunerpro do. Thanks, again I am new and trying to learn.

 

You don't show a datalog or mention your blm or afr . Start with adjusting ve the ae if needed. Read the DIY stickies

 

To the first order it sounds to rich. But yeah need to see the data logs.

In TBI section is "come in free tune" in stickies. A worth while read.

Step one is set BPC. Then ECU knows how much fuel you flow.
