Not sure what to think about those #'s. But I am going with the JLT with SCT tune. I spoke with Doug from bamachips on the phone today and he said the big daddy cai is not even close to a c@l or jlt due to the maf sensor or something along those lines..(uses a ford lightning maf or something??) I am getting rid of the big daddy.

 

Yea let me know if you dyno, I'd like to know your results. I know we were doing a lot of pulls and the engine was starting to warm up pretty good . I'm still thinking about the #s myself but I want to get a WOT on dry road to see if I can feel a big difference.
