I've asked this question a few times to different people and have gotten completly different answers. I have a street proted motor, a highflow cat, an intake and a catback (RB). Would installing a downpipe with my set up give me boost creep? Can i run this set up on the stock ECU for a while or do i need to upgrade the UCE and get my wastegate ported?

You need to get a computer (Power FC) before you put on that dp or do anything else.

i said nothing about the mid pipe. I have the highflow cat in there right now, would putting in the downpipe hurt the motor? or can i run it off the stock UCE for now?

I meant dp. Buy a power fc before you put on the dp.

You will most likely creep. You need to get your wastegate ported, for either ECU. A PFC cannot physically decrease creep. The only thing you can do is tune for increased boost, but that's half-assed at best.

HE IS NOT GOING TO CREEP WITH A HI-FLOW CAT. The stock ecu can handle a mild streetport at 10 psi, but going with a TUNED PFC would be better. Just like we answered you the first time. The only reason you are getting different answers is because you aren't listening to the experienced owners but a bunch of newbies who aren't in the know....

Unless you want to go crazy with mods, a Pettit ECU would work with your current setup also.
