Service Engine Light

[Coonskin20]

I just recently installed the ts performance 6 pos. switch and a new intake. When I have the chip on 75 100 or 140 and I accelerate hard, the service engine light comes on and my truck stutters and doesn't wanna accelerate. I read some that my stock hpop isn't strong enough... any ideas? Thanks.

did you read for codes, Is P1211 present? do you have a way to monitor ICP and IPR DC?

You need to read codes to see what the issue is. It could be overboost (P1249 or P0238) or it could be ICP not keeping up (P1211). Both of those issues can cause the same symptoms.
