SS, check with tst but I think leve 7-9 will blow your relief valve and are more or less for the hard core only. I saw 27.5 on level three and have never been over that. I dont even use it now that I got the mp8.

Is the R49AP the one with the pressure, or is that something even newer? I have never seen the AP.

 

Talked with John this afternoon about this issue. He said his dual CP3 setup will definitely support two high pressure CP3s. That sounded good to me since I already had one. He's down and sick right now but he has his prototype about ready for Sloverado. Can't wait to hear the feedback on that tune. I think Sloverado has a pull coming up soon. Good luck.

 

Yup I am hoping for dual modded cp3's for the dyno Feb 17. I will have dual cp3 for a truck pull March 17th for sure. We will just wait and see.

 

I wish I had dual pumps... my stock cp3 hates me.

 

tst says level 2 is safe. the owner reccomended no more than 2. It is equal to high levels on the edge ez. how much rail pressure does the mp8 add at 50% ? anybody have the answer

 

I will have to double check but I think it will spike it up to around 26-27k at 50%, on my truck anyway

 

TST only fools it to make pressure tell about 2500 rpm's then it kind of strays back to stock. Any thing on my truck over 5 will put the truck in limp mode. I have had long talks with Mark at TST and found all the info about it I needed.

 

Hey Sloerado, is that what Mark said at tst that the tst only boost fools up to 2500? Cause I notice on mine I hit 58 psi of boost, then at 2500 it drops about 10 psi of boost. So that would make sense I guess why im loosing boost on the top end. Is there any way around boost fooling the top end above 2500 rpm?

 

With my mp8 plugged in first I cant tell that the boost fooling is falling off, but I am not runnin boost #s as high as you guys either.

 

At 659hp on a stock cp3, we all hate you too. Just kiddin'.

 

Lol! Will I make twice as much hp with 2 pumps?!?!

 

See maddog I was having some problems with TST for awhile. I have talked with them and they sent me a new one and harness. I have it on the truck now with no problems. I am not sure about the boost fooling as I run a HTT plug in mine. It seems it have something to do with the pressure as I saw the same thing as you but it would through a code (rail pressure code) and loose all power. That was on any setting over 5. The 7-9 on the twins setup you need a rail cap on but I can't get that high and I have mine capped.

 

please explain your have your rail capped?

 

Yes it is capped. I took the pressure relief valve out and put in a cap so I can run as high or rail pressure as possible (safe though). Some valves are weeker and will blow before what they are made for so I took that out and capped it.

 

how much is a dual stock cp3 kit? what is the difference between this kinda set up and a fass or walbro system? I am not real up on the fuel system stuff..... probably should be.
