I read an article in some sport truck magazine about the Bully Dog power pup module for the Hemi. It showed dyno results of 25hp at the wheels.
Any opinions on this product?
How does it work with the 07 Hemi with the MDS? Test was on an 06 Hemi, which I believe also came with the MDS although the article did not mention it. The Bully Dog website also only went up to 2006 year with no mention of the MDS.
Of other interest in the article, it stated that the rear wheel hp of the Hemi on the dyno was only 211. Is it just me or does this seem low to anyone else?

I am still working on posting pics of my truck.

 

The 07's are different than the 06's when it comes to programmers. It took Superchips a while to release an update to support the 07's due to some differences in the pcm (not sure what). I have heard though that the MDS hemis dyno lower than the earlier hemis (I have heard about 240 hp as opposed to the ~270 hp on the non mds). If this is true, I would guess it is due to a modified cam to make MDS operate properly.

 

I have a 2004 Ram 1500 Hemi With the power pup and I love it. I have noticed a lot of low end and mid range power increase. I also noticed about a 3-4 mile to the gal. increase around town.I am ordering Edelbrock headers today, hope this helps.
