Listen, I get it, this is not my first rodeo. Have owned many forced induction cars in my life.
I'm mearly saying that it would seem as of late, some of those accepted thresholds are being challenged pushed with great results. My personal experience on this platform, 2 R's currently, hasn't spelled the doom an gloom that is perpetuated by many over the years. True tomorrow anything can happen, but so far on not 1 but 2 R's I haven't had a single issue and other brand tuned R customers have only been impressed/pissed, so I think UM knows how to tune these.
Once again, really, I appreciate the information and opinions even if I disagree with some of them. I think it's great that there are so many enthusiasts out there and awesome that there are so many options for us to choose from. It's great to discuss/argue with each other as generally, we are all looking to achieve similar goals.
My main point in starting this thread, was for those already running UM's aggressive tunes, probably set somewhere between 27-29 peak psi, depending when ya were tuned, if ya had bumped it to 30, as there are topics on it in UM threads on other forums, or if you'd bought the cable and adjusted your loaded adjustable file yourself after conversations with Fred etc
I understand that some have always thought that their aggressive files are to aggressive, I'm just not one of them. I have nothing but smiles and great things to say about them personally! But it has become apparent that they are not nearly as popular on this forum as they are on others, no biggie, this thread did teach me that
I'm not looking to argue any points because it's clear you've got it figured out for you, but my point is pushing the turbo like this, 30 psi being just a number, has risks. I'm trying to give you a more realistic perspective that there might not be a second free lunch and you could actually be hurting your overall performance to see 30 psi on a gauge.
It's not about what is "too aggressive" or not, it's about what makes sense and unless you've done some actual dyno tuning back to back my hypothesis is that you're seeing very little gain by pushing peak boost to 30 psi. You've created more heat, increased load on the turbo (accepted thresholds be dammed), and might have nothing beneficial to show for that. More risk than reward. But that's not what you want to hear.
Now if you've got back to back dynos showing that this has a real overall benefit, post it up! I'm not saying I know I'm right, or that running 30 psi on your UM tune is absolutely bad, but I do know that when you're dealing with a static turbo compressor map and you're actively pushing the turbo outside of it's efficiency range, you're going to have a bad time.
Also the thread title didn't really direct UM tuned Golf R owners to discuss why they have their tunes set at a certain PSI, and I don't really see the point of actively limiting the discussion to that tuner and being disappointed in the forum when you don't get an echo chamber from it.
Anyway, hopefully some like minded chap hops in and shares his experiences like on the other forums.
