What do your guages say? boost? fuel pressure? pyro?

Welcome to the DTR!
I am pretty sure that your pump VP44 is timed electronically. Not like the ole 12v motors. that's why we add timing box's to the 24v's. I think the tranny shop should stick to tranny's.
I'm sure someone will chime in about the boost problem. Maybe too much air for the stock injectors and not enough fuel. A Smarty might cure it?

20 psi at wot pyro reads400-600 i don't have a fp guage i do have a bd low press light thanks guys good to be here

tookmyname

the shop is a fairly reputable they said the keyway shifted on the old pump

Sounds like a load to me?
Only way a pump can slip on a 24v is if the key breaks and would doubt that happened. You need to see what your FP to the IP is before you can go any farther. I am assuming you have changed the FF recently?

does the truck have any codes in it?

tookmyname

they cleared all the codes both pumps were replaced and the filter too.the 1st gear band is slipping but not that much thanks again guys for all the help.

how do i check the timing i was told i should run more timing with the seetup i have

Copenhagenjunkie

U can't check timing, it electronic and can only be changed with a fueling box. To me your boost seems low, I wonder if the wastegate is stuck partially open? What do you think members.........

could my apps need to be reset?

When did the problem start?
Did you JUST get the trans installed?

i just reset the apps and that didn't work but i did find a leak i'm trying to track down it seems to only leak when your in the pedal

A boost leak?

The Edge Juice with Attitude is very good box with gauges and lots of safety features, best bang for the buck.
