If you have been reading my posts you know what I have

09 RCSB Hemi 4x4 Sport with 3.92s

Simple bolt ons... Mufflex 14, Superchips 93 tune and recently added the K&N CAI.

The truck is now turning 5.7 0-60s, happy considering it is a 4x4.

But the point of this post is MPG results. Keep in mind I went from a stock airbox with a K&N drop in to a K&N CAI.

I found I lost a couple tenths with the CAI over the drop in. Very marginal loss, but still a loss over what I had. It did seem to help slightly performance wise.

 

Your times are impressive, thanks for posting up. I have stock exhaust and just a drop in with the programmer. My best 1/4 to date on the data loggersaturday (corrected) was 13.9 and my best 0 to 60 is 5.9 so I have a bit of work to catch up to your times. I think the exhaust has to be next for me. My MPG went to hell wth the 93 tune but I dont really care too much about that. I remember you saying a 5.6 0 to 60 was going to be tough for our trucks, maybe not I am not so happy with my off line performance at all (could be the driver sucks) but the top end on these trucks is amazing.
