Re: 90 - 91 chip (awsumm)
They are interchangeble.
Will be some minor changes in some parameters but not enough that you would know without downloading the bins and comparing them.
You DO need the MemCal from the same type car/engine.
ie; a V6 MemCal WILL NOT work on a V8 Camaro/Corvette.
It also CANNOT be reprogrammed to work correctly.
So just make sure what you are getting the ECM/MemCal from has the same number of cylinders as what you want to use it on.
