The problem is with my LLY in the sig, with Edge out and only a 90HP Westers's tune...For Reference.

Anyway, I replaced the fuel PRV today, but had to end up taking out the entire fuel rail because the PRV was so darn tight. To make space, I removed a downpipe of the turbo on the drivers side of the motor...put everything back together and now this code.

IS IT POSSIBLE: That the down pipe is not properly secured in the blue rubber boots or not clamped tight enough and this is the cause of the DTC??

Thanks for the help and any advice!!!:help:

p0238 is caused when you exceed 36psi in two consecutive ignition cycles.

My big turbo can make 70psi, so I'm told, haven't gone there yet.
wanted to know about the stock one not your BIG turbo and good luck keeping the heads or head gaskets on if you ever do hit 70psi or do you have some upgades to the heads and head bolts or studs if you have them

with a boost controller the stocker can make almost 40psi, but it won't last very long, I'v read around 34psi is a good safe number
