My question is whether the turbo tables need to be remapped, as tree said above. Because if they do, I need to start getting in touch with the right people. The other ISX CM2350 sits below 34 PSI, and the X15 CM2350 stays below 32 ish PSI.

Just got curious about the turbo speed.

IS THIS TRUCK DE-MANDATED? ... IF NOT, AND ALL THE EMISSIONS ARE STILL ACTIVE .. THEN YOUR STATEMENTS ABOUT BOOST ARE INCORRECT!. IT NEEDS TO BE LEFT ALONE!. I have seen at least 100+ times where some model cm2350 trucks will get to 38 psi boost, when all the emissions systems are in tact.They ran just fine. - It all depends on what tier, that CPL, what engine modes it happens to be running in, and a lot of other factors.

Just make sure the turbo is the right part# for that tier engine. Then also make sure the program is the one that belongs in that engine/truck... and that it matches the engine serial number according to quickserv.

you mentioned doing an EGR tune-up.. This implies that thing is NOT de-mandated.

================

HOWEVER...

IF IT IS DE-MANDATED.. THEN YOU NEED TO GET THE WHOLE PROGRAM LOOKED AT TO ENSURE IT IS CORRECT.. Because I do not know of anyone who is worth their salt at all that would let a CM2350 get as high at 38 psi boost AFTER a delete has been done. That much boost after a de-mandate is absolutely harmful, as there is no more EGR gas or combustion control to handle it. On a DELETED/DE-MANDATED CM2350, it is not uncommon to see it that high, because no opne made any corrections. Without egr gas, etc. this will cause the engine a severely shortened life.

Figure out what you are referring to... is it de-mandated or not?.

Maybe the 2 scenarios have gotten confused in your head somehow?. otherwise you question is not making much sense to me.
