Car was surging at wot. I did a search and one said pull the top chip on the WS and I did spray works fine. Problem is I do not want to spray my 4l60 through the shifts. I dont know if my chip was to low or the switch is bad. I had a 6200 chip in it my rev limit is 6700 and I shift at 6500 or 6600. I dont know if it will do better with a 6400 or 6500 chip in it. The thread i searched said he fixed his problem with a chip change. Has anyone else had this problem, if so what was your remedy? thanks for any help.

 

Sounds like you are feeling the car nose down from the nitrous shutting off before shifting. THe only fix is to put a different pill in it so it does not fall off for so long.

Thanks Dave, Im gonna try a 6400 or 6600 pill.
