Brand new to this, Take a look

[Atkins]

The combo is a 408, L92 Heads milled -4cc, l76 intake, stock maf, cam is 238/254 605/596 114+4, th350 trans, tci 3600 stall. tsp 1 7/8 headers

Ok the tune attached is a mail order I got for the 408 with 243 heads, ls6 intake, with cam 238/240 605/609 112 all else is the same.

Here are the DTC's
[PCM] P0103 - Mass Air Flow (MAF) Sensor Circuit High Frequency (SES) (Old) (History) (Immature)
[PCM] P0134 - HO2S Circuit Insufficient Activity Bank 1 Sensor 1 (SES) (Old) (History) (Current) (Immature)
[PCM] P0443 - EVAP Purge Solenoid Valve 1 Control CKT (SES) (Old) (History) (Current) (Immature)
[PCM] P0530 - A/C Refrigerant Pressure Sensor Circuit Malfunction (Old) (History) (Current) (Immature)

I have deleted the A/C, Evap, P/S, EGR., AIR
Do I just disable ses on those items in the DTC menu to fix those.

Another issue is the idle, rpm raise then drop will cause it to attempt to stall if I do not "massage" the throttle.

If you guys could just give this a glance and point me in the right direction it would be much appreciated.
