Boost and surge....
This only happens at around 30mph and 45mph. Say I'm cruising along at either of those speeds and approach an incline. I naturally step on the gas to maintain speed up the hill. As I do this, the transmission seems to stay locked up, RPM'* do not raise, boost starts to come on to about 3 or 4 psi. When approaching 4psi, the engine starts to surge a little, assuming from getting boost at low RPM'*. If I push the peddle to close to half throttle, it will downshift and the boost goes away..... Any ideas?
