Message: [QUOTE="Smith505, post: 423336, member: 7860"] -------------------------------------------------------------------------------- I recently posted this on another powerstroke site and couldn't find an answer. Maybe you guys can help. I wanted to upgrade my e99 xle4 PCM with a xc3f strictly for the better shifting strategy. Once I installed the xc3f it was like the truck was in limp/ valet mode. I've tried 3 different pcm's all with the same outcome. From what I've read any nvk2/4 should be plug and play. Any ideas? Thanks in advance. Btw my truck is a e99 crew cab long bed 4x4 automatic with t500 straight pipe and air intake. [/QUOTE]
