Your throttle body is probably sticking in the higher rpm's.
I had that same problem with a Mac 70mm TB and I couldn't
stop it from sticking in the rpm's so, I ended up throwing it
in my trash can and buying a BBK 70mm TB.I never had a
problem since.I never had any problems with the stock TB
though.
