Yesterdays dyno went great!! I just did the 93 tune since it was what I really needed this summer traveling back and fourth from Maine to NY. Only Maine had 91 but everywhere else I went had 93 so I wasn't on the best map 80% of my trips. I pulled 294/330 on their Mustang and was extremely happy with results. I'm still not using enough fuel to even max out my stock pump and injectors so the fact that I changed to 750's and the 65c pump were just a safety buffer but not needed for the stock VF52. It doesn't hurt to have them in but I found that I'm technically still just a Stage 2 so I'm really happy with the results.
The EBCS is working but creating tons of flutter at almost 22lbs of boost. Now that the tune is done I'm definitely thinking of pulling the EBCS and going manual set to 21 or 22 lbs. Since I have it already I'll just swap and see if it stops. If it does, I'll just have to lower it to 20 when I'm on 91 octane.
EFI likes the MBC but doesn't trust a lot of their customers in having any control of their own boost. Lol
In order to swap over, its just easier to do it after the tune so I don't have to try to convince them that I won't be turning it up as high as it can go once I leave
