I have a 99 cummins auto that is sick. It's throwing both P0238 and P0237. So I replaced the map sensor... Didn't fix it. It has 100hp injectors and a Quadzilla pulse v2 and it will usually blow black smoke on stock. But now it won't plus it is very sluggish almost like it is in limp mode. Before the problem started I replaced the terminals on the batteries. Oh and plus it surges when it shifts into overdrive and when I climb a hill from a dead stop with overdrive off it surges at around 2500rmp. When I pulled a trailer the other day with a car on it it would surge going about 35mph. Please help me!

search googlw for moparman. he has the dodge write up to tracing issues with the map sensor. since you replaced the map sensor I would think your wiring is the issue. your isssue might be with the quadzilla boost fooling
