So, I'm pretty new to the KA-T world... To make a long story short, I blew my first KA when I went turbo, tunes it with the SAFC II but didn't have a 24/7 wide band going. Tune slipped.. BOOM! So, replaced the KA and went 5spd all in one shot. So, over the passed few months I've had to consistently take more and more fuel out of the tune and not sure what could be causing it.

Current Setup:

Garrett T3/t04 57 trim. .48 a/r
SR 370cc injectors
Walboro Fuel Pump
Stock MAF
Auto ECU

I started at about -30% while cruising, not in boost, and have since had to almost max out the SAFC current settings are -32% at idle, and -48% at lo-thrl... Is this normal? What could be the culprit? I feel like I shouldn't have to be taking out soo much fuel...
