Default 2003 WRX Stage 2 ACN 91 LWG DataLog

hey guys, 2 days ago i went stage 2 , and flashed the ACN 91 Stage 2 map. on the freeway in 4th i went wot and realized the boost was really high (19.3) to be exact, so last night i loaded the LWG ACN 91 stage 2 map and today did 2 3rd gear pulls while data logging for you guys to check out because the only thing ive ever tuned was a Holley double pumper
Also wanted to post up because it feels weak, The feel isn't much different from stage 1.

The second log needs the permissions set to public.

Because the older cars can end up having various mechanical issues that typically impact fueling, I would drive around on this map for about a week or more without reflashing anymore maps or resetting the ECU (or disconnecting the car's battery). Then we can look at your long-term fuel trims (A/F Learning 1 A, B, C, D) and see if they are within reasonable ranges. Should be within +/- 5% with outside of +/- 8% indicating a possible problem. But, they take some driving to populate accurately.

One of your A/F Learning values is on the high side (almost 8%). I would get a pressure test of the intake tract done. Even though the wastegate lines might be intact, check for cracking or other damage on all sides.
