What Is This???
 

Curious as to what this is? Im guessing its for rail pressure some how some way and how will this allow up to 65hp by allowing the rail pressure to read more psi? Fill me in....eBay Motors: 03-07 Dodge Ram Cummins 5.9L CP3 Chip Tuner Programmer (item 160254809210 end time Jul-05-08 09:22:11 PDT)

It's just a rail pressure sensor with a different calibration. It basically lies to the ECU and says the rail pressure is lower so the ECU will command more pressure. If the commanded pressure from the ECU is say 23000 PSI then the "calibrated" sensor from SP would report the actual rail pressure at 21000 PSI then the ECU will command 2k more thus resulting in an increase of HP/TQ.

its not even worth the money
just cap your rail .02

more rail pressure means better atomization for a better burn

don't forget to add faster wearing injectors too..........:argh:

and wearing of the pistons :f:

Ha whoa.... :poak: :nshock: How many miles were on that motor?! One thing always leads to another :pca1:

miles i dont know, its a daily driven 10 second truck.

But hes running dual modded cp3's and maxed out rail pressure. also turning out 4500+rpms

cool, I dont remember seeing pistons with the optional Flower pattern molded into the top.
Looks expensive!

theyre lighter than stock:U:
