Has anyone ran into this problem? Today I installed my arson cp3 pump mod and eliminator fuel system. I was driving put the pedal down in 6th gear and threw a code p0088 fuel rail pressure signal above max limit. I have fuel psi set at 15@idle. Whats causing this code or how can I fix it. I was running smarty 4.4 than had Bob send me 4.2 but when i plug my smarty in its reading v4.10c....any info PLEASE help. 307-214-3330 Brian

 

bump to the top

 

normal code for modded cp3 get a pressure fooling box and you will never get that code again.

 

The latest Beta 4.2 is a 4.10C tune.

 

thanks for all the help...tst in my near future i guess? will the new tnt tune fix that? what are you guys reccomending?

 

so i just ran my truck again...no code this time but you can feel it lugging as if its cutting back on fuel...any suggestions?

 

to the top...

 

could the pump in combination with the 4.2 be screwing with the truck some how? It almost feels like it is surging any ideas

 

anyone????

 

if you are running it on sw9 it could be cutting out if its not getting enough fuel. as for the code I get it also on my truck like Rpainter said its common. I just clear it out and keep going

 

than what about the surging im getting as if its derating?

 

Possibly your RV leaking. Try capping the rail and see what happens
