Yeah Mopar makes a cold air kit for the 5.7 and the 6.1. Maybe the chip I was looking at was made by somebody else but I remember when I found it they advertised it for the Hemi, with gains of 10%. I'd personally rather have Flowmasters but that's just me. I went to Mopar.com and they have new programs for the auto-stick I thought that was interesting. I know they have ECU's that put out a substantial increase. I saw one program that ran off windows and was like 2k, wow. Pretty sure that one wasn't street legal though.
