Yes. Before porting it got 15.89 up to 805 at stock pressure (this is with c88 machining plenum)
After 4.1mm port job and bumping the reg pressure up to 2150psi I got 15.89s up to 845fps. After increasing the ports to 4.5mm and adding weight to the hammer spring I've got 17gr slugs up to the 850s, 18.1s up to 835fps. 27ft lbs.
If you're keeping the stock tube I recommend adding a half turn or so on the reg and adding a plenum. This will get you in the 780/790 neighborhood with 18.13s. and near 825 with 15.89s

As far as accuracy. Damn impressive.
I've found in the 380.mm superior several insanely accurate projectiles.
1. JTS 18.13
2. Griffin airgun ammo .218 LDC HP slug 17gr
3. AEA 15.89
4. JTS 16.08
5. FX Atomic.
