Less boost with Forge pipes

Anyone install Forge's hard intake and intercooler pipes and test boost PSI before and after? I seem to be having some trouble with mine. Using the stock pipes on my RPM Stage 2 tuned F56 S I was hitting 21/22 pretty regularly with the highest being 23.4. After install I'm hitting about 16-18. Highest I've seen is 18.2. All of the connections seem good and I can hear the air moving much more than before but I don't think it's the sound of a boost leak. But with a drop in PSI that big I can only think that that's what it is. Might just have to have a shop do a smoke test to make sure there isn't a leak.

So far I am running the Forge intercooler with FTP charge pipes, I don't have any boost losses after the installation. Could potentially be a leak but I have heard that the FTP pipes vs the Forge pipes are different

Did you take the four rubber o-rings out of the old inter-cooler pipes and put them into the new ones?

Yup, all are installed. And of those 4 rubber seals MINI only sells 3 separately. The 4th can only be gotten with the $300 OEM pipe. Guess how I know.

Again, the OEM rings are on the pipes. We took them off the OEM pipes and put them on the Forge pipes. One pipe came undone while driving and the seal was lost. That seal has been replaced after buying the $300 OEM pipe just to get the seal. All the seals are there.

You missed my sarcasm. We didn't know about the rings and installed the pipes, then the CEL fun came on. The Forge instructions didnt reference them

Yeah, it went way over my head. At least yours had instructions. We had to use your blog for the install since ours didn't come with any and we couldn't find them on Forge's site. The driver's side pipe was already on when we realized we needed to reuse the OEM seals.
