Creep with Hiflow cat?
SOMETIMES, when im at WOT, my car gets creep. Boost flunctuates, but i have a high flow cat. This happened after my tune and usually happens when im in lets say 4th gear at WOT at 60mph when their is a lot of load. IM boosting approx .82 on the PFC.
Why is this happening? Ill try to attach a video also of my boost gague.

Why do you think it's happening ? A high flow cat increases flow over the stockone, much like adding a midpipe. Most everyone on here has read at one time or another that a mid pipe with a down pipe and cat back will cause you to have boost creep......dose the word cat confuse you into believing it flows the same as a stock one?

/\ Agree with rynberg. Get a boost controller. I just got my profec-b spec 2 in and am doing some fine tuning now and it seems to be pretty well controlled. Currently my peak hold is 13.2psi but while I was tuning it I had settings that were making me hit 14.6psi. I'm trying to get around the 14.5psi mark and the boost controller is holding those values pretty well as I set them without any creeping. Of course I haven't ran into a real cool night yet so we'll have to see if it creeps any then.

Stock solenoids are old... 14 years old...... time for a new aftermark controller.
I suggest the Blitz SBC I-D III... great controller, relieable, easy to use, uses dual solenoids for sequential control, and works with internal and extrernal wastegates.
If you dont want to spend the $500+, manual boost controllers work great too.... Turbosmart has some great products.
