I did the same thing as Lost in Isaan, I renamed the CS_B52 folder before installing v1.1.

The CS_B52_interior.mdl file, is bigger (12,557KB) than is was in v1.0 (10,993KB). This is right because we can see the wings and engines in from the VC.

The fuel panel does have the fuel flow lines and looks a better (IMO) than the modified texture, by HeavyEng and TurbofanDude, in the mod.

I can't remember all the spelling mistakes, but there is one that is still there: 200 KNOTS MAX DURING REFRACTION.

I'm not sure about the power/performance, but I did a test down the runway (B-52 Cleared for takeoff (KNKX)) and v1.0 hit the wall at the end of the runway at 290 knots while v1.1 hit the wall at 256 knots, so the thrust is down a bit so it isn't quite the rocketship of v1.0.
