MP-8 for 6.7

[JohnBower]

Has anyone tried the TS Performance MP-8 on their 6. 7L pickup? I noticed that in the installation instructions for the MP-8 that they modify the fuel pressure valve and connect to the fuel pressure sensor. They imply on their web site that connecting to the map sensor allows them to modify timing but they don't connect to it on the 6. 7. Do you have to stack another system to modify timing?

Also does the MP-8 help fuel mileage?

Stay away from the MP8. I used one on our trip towing heavy out west and had nothing but trouble. No mileage increase. Just thrown codes. The Smarty is the best for the 6. 7L
