i am still getting a CEL after installing a boost relief valve. i started to get the light after installing the Edge J/A. i am guessing a weak HPOP, but was looking for some advice

Is the light staying on or does it go out after a few minutes? What code are you getting? If you are getting P1211 that means the ICP pressure was less than desired for a set amount of time, usually a few seconds. Is the light coming on at about 24-25 psi of boost?

That doesn't sound right, you will have to pull the codes to see what it is giving you. Could be a oil issue, but need a code to verify what is going on.

Mine does that too. I don't have the boost fooler or anything, but it'll do it with less than 15psi. I just installed a HPOP pressure gauge and that thing will stay low for a long time and then I get the light. It'll stay on for a while and then go off. That's probably what's happening. Your tune is firing your injectors faster than what the stock HPOP can handle. I guess you could do one of three things. 1. just drive it and don't worry about it (mine's been that way for a couple of years now). 2. get a new tune that will fix the issue. 3. Get a better than stock HPOP and never look back!
Like I said, mine's been doing it for close to two years now and it hasn't seemed to hurt anything. I would like to get an Adrenaline HPOP but I just don't have the money right now.
