how bad will that drain the rail? prob need a modded cp3???

 

With just the bullydog and no injectors you probably wont be able to use all of the % of the mp-8 if you do your truck wont be able to tell a difference in how it runs and the motor will start to clatter like crazy.

 

Well i gained 75HP when i DYNOED! with the MP-8 that was stacked with my PMT

 

is the clatter very bad for the engine? i mean they already clatter like crazy compared to a gasser.

 

i heard the mp8 doesnt work with 2007 5.9l's?

 

It works, TST is the main one that wont work.

 

Anybody know what is the highest I should let the fuel rail pressure get up to?

 

i think its 26500 isnt that when relief valve pops or somethin im interested to

 

Yeah I think it is something in that ball park

 

I gotta ask...new to this great world of diesel....what happens when relief valve opens and what needs to be done to reset so to speak?

 

I just went to the track last night, for the first time since i had my mp-8 in, looks like i gained about about 4 tenths with the mp-8. i had her on 100% with the CL and had no problems. but then again its only a 1/8 mile track.

 

MP-8 works like a champ. Just put it on this morning at work, and just got to open it up on the way home. Outstanding buy....thanks guys for the feedback I really appreciate it!

 

27500 is the blowoff point once you blow the relief valve you must replace it with new one. Most when they get up around that psi just cap the rail.
