With all the concerns about running lean with a CAI i was wonder if any one could tell me how much to richen up on my programer. I am stock engine wise other than an S&B CAI and the diablo predator. I also have a 4" rancho lift with FCII 35's. Thank for the help in advance.

 

pretty sure you can only change timing on the programmer, need to have a custom tune written to adjust air/fuel. or i could be totally wrong

 

You actually can adjust at 2 different rpm ranges. I not sure what they are, but i know you can. I know i can get a custom tune, but diablo says the a/f should be fine, but they don't deal with s&b alot so there not sure. I would like to dyno and get the custom tune, but dont have the money for it which is why i was hoping someone would know. Thanks
