I think you may just need to give it some more time. I've ridden with some strong guys switching from mtb to road. Road riding at speed is very different than riding trails.
It takes time to perfect your position and it takes time to learn how to go fast on the road and especially with a group.
There was an expert level mtb racer who did the shorter rides with the fast guys in my road club. He did pretty well but he was exceptional plus he had a super light XC bike.
