Please Help, MEFI 4A Sucks, Ram Jet 350

[64malibu]

Is there any other option than purchasing this MEFI4B from MSD Fuel Injection ($1300) or the one from AZ Speed and Marine ($600) in order to reprogram a ram jet 350 for the GMPP Hot Cam and Fast burn heads. I'm working with a limited budget and also do not have access to a shop with a dyno to tune the new ECM. I've googled myself blind trying to find a solution to this, I found several tuners that claim to be able to bypass the password part of the MEFI4A, but there is just as many other tuner sites that say MEFI4A can't be tuned b/c it is locked.

If anyone has an economical solution to this delima I'm all ears, I just can see throwing away a brand new MEFI4A just to be able to install cam and heads, the GMPP hot cam is not that much more radical that the factory Ram Jet cam.

PLEASE HELP
