Not sure with the radix but I am running 17* with 12 psi on the STS. Just give it a try but be sure to log and watch for KR. I think you may be able to go higher but I am not sure how safe it will be and will depend on how the rest of your tune is set up.

I cannot tell wherhe the sound it coming from. I thought it may be where I have not retorqed the radix back down after it being on a couple of weeks, but did that and it still makes the sound. I don't think the speeds up with engine rpm....at least I can't hear it....????Always something!

yeah I am not experiencing any knowck ...at least for the few minutes I watched for it, but today for the first time I have some "missing/sputtering" at high rpm. Shortly after that I have a horrible metal to metal knocking/clicking/rattling sound I cannot tell wherhe the sound it coming from. I thought it may be where I have not retorqed the radix back down after it being on a couple of weeks, but did that and it still makes the sound. I don't think the speeds up with engine rpm....at least I can't hear it....????

I dont think there is a basic formula for X amount of boost = X amount of timing. I dont think 15 degrees would be a problem, but a log is the only way to tell.
I would be sure to log and see if it is KR. The 2.9 pulley is deinately going to generate more heat. I hope the knocking is not internal engine damage.

Yeah I am detonating too! Its very audible, but just sometimes. The horrible grinding noise is less today, but I think I have tracked down where its coming from...the nose of the charger...
Was alot of work
