Just bought the ARH Headers and looking to get the Hemifever tune on my 09 ram hemi. Anyone know what to expect from getting the tune? Is it that much of a difference? Just curious. Thanks for any info
I came across a vid on youtube of a 14-17 ram picking up 50-60hp with the hemi fever tunes and longtubes, not sure if I believe it but there was dyno sheets to prove it. The stock manifolds look really restrictive so I think you'd pick up some decent gains with that combo. Plus longtubes would sound nasty!
