Wanted to make a new thread covering the most recent revision TPC Performance Housing turbo variants as the last one got locked and pointed to their OEM IS38 replacement. Just to be clear, this thread is not a discussion about the IS38BB that TPC offers since that thread already exists. Deleted my old post in the IS38BB thread so I am not spamming multiple threads.
I swapped to the newest revision TPC38 and came from a standard housing Vortex. Overall the Vortex was a super solid turbo. Great spool, took all the boosts, fantastic price during the Boost Weather Sale.
Was gonna move to the XL housing, but had the chance to jump on the 38. Wanted more top end.
Here are my initial 93 tune results on the new TPC38 with Performance Housing. This is the variant with the bolt-on inlet, 70mm TIP outlet/compressor housing inlet, and 56/71mm compressor (vs. the Vortex's 54/71mm compressor; nominal difference, but bigger is better right lol?).
Modified the WG/PUT/PR maps in ED and ran some custom cam timing maps courtesy of @railroader. Currently running 93oct, but the tune is otherwise identical to my Vortex tune.

Hoping some other new owners will chime in with their experience.
