check engine

[materi]

I recently installed a tw chip and when ever I get on it real hard in either tow or extreme my check engine light comes on and truck runs a little rough but once I shut it off and start it up the light goes out and the truck starts up and runs fine.is it the truck or a glitch in the chip? Will a regular obd 2 code reader be able to pick up the codes?

that is a overboost code it just shuts fuel down when you hit a certain boost

That is prolly the 1211 ICP high/low code, the OBS trucks don't throw a CEL for overboost.
