05 Mustang GT reduced power mode after tuning

[My90Iroc]

I recently tuned a friends 05 GT with just a cai, shorty headers, and exhaust. Now when you drive the car around the block we get p2105 and p2106 and the car just shuts off. What causes this?

You changed parameters that most likely did not need to be changed. Did you copy some other tune or did you write it yourself?

Might be the tune for the CAI. P2106 is Forced Limited Power and might be cause the MAF. Did you use the scanner to check for the STFTs and LTFTs? They might be way off.

I did the tuning myself via wideband. The car was lean before tuning began and now is running in the low to mids 12's at wot. I tuned it like the older fords via the maf table.

Easiest fix is to raise the wheel torque error way up.
