Ok I jusT got a 91 ss with automatic transmission. When I accelerate hard the rpm goes up fine then it just drops 1-2 k. Then goes up normal and back down 1-2 k. Not sure where to look. Also got boost set to 1bar.

Is it shifting gears?

Does this change in rpm occur when you are just "cruising" not have much throttle input? If so, it could be the torque converter locking up.

Can you take a video of what your describing?

Thanks
