OBD2 Codes (EPC light) Boost problems?

If I give 75% or more throttle in 1st and 2nd gear my car hiccups/stutters/sputters etc. until I let off the gas then itís fine again. After a couple of times and EPC light will come on. It doesnít go into limo mode bc I still have plenty of boost even after the light.

I recently had a friend pull these codes. Iíve looked them up but donít know what to think any help is appreciated.

Only mod is JB4 on Map 1. Iíve tried different maps, reseated the connects etc., but that doesnít seem to change anything.

Get a real code reader. They're cheap. Clear them and try it again. Also, how old are plugs? Checked em lately? What happens if you put it on map0?

Plugs only have 5k. Thatís the first things I checked. No problems there. Havenít tried Map 0 yet. This problem has been occurring for a few weeks/months so I know itís not a one time occurrence
