Well I knew I shouldnt have but I did, my cat was messed up inside so i had it deleted.... well it ran great for a day or so. then I hit fuel cut.. my boost gauge "stock" maxes out.... I even bypassed the stock boost solenoid, the only thing that did was slow down the spool? but eventually rises to max.... any fixes besides an external gate.

i had a manual boost controller on my truck when i got it and when i cut my cat i just turned it down some and it seems to work fine, i still peg out the factory guage but don't get and overboost shutdown

I get that same problem from time to time. I just don't punch it on really really cold nights. But i have an External already to go on. Just gotta get the DP made.

Adjust the wastegate (make it longer) and get a cat. On cold nights, I have issues with high flow cat (I also have a scoop/ported exhaust housing which is supose to help.)
