06 F250 has low boost?

[TwinTurboStroker]

Hey guys I have a buddy that has a 2006 F250 and he has an SCT from Eric and it runs great.....but here is the thing, he drove another 06 F250, stock, and he said it was putting out more boost 25-26PSI than his truck.....he said his truck was only putting out about 20PSI.......I thought I read that these trucks should see about 26 to 27PSI?????

I used to see 28-29 psi stock. With Innovative tunes I never see over 25-26 unless I am towing, then the max I have seen is 30 psi. I know Eric keeps the boost down without studs, but 20 sounds low. Does he have a good gauge? The factory gauge can be 2-4 psi off from what I've seen.

Yeah thas what I told him about the head studs, considering he already had them replaced, but the dealer wouldn't do the ARP.....I figured Eric might keep it down to be safe but I do think 20PSI is low too....any ideas as to what the problem might be?

i would tell him to talk to eric and see what they think. i would bet its just the tune that he is running.

Yeah I should probably ask him if he told Eric that he already blew the head gaskets and they just put stock head bolts back in instead of the head studs
