Cheap, not that I'm aware of. MSD produces what's called a BTM or Boost Timing Master ignition module that can retart timing up to 15 degrees in 1-3 degree-per-psi increments but it may need to be modified to work with a dizzy. It is an ignition module in itself(amplifier) and works well with single coil ignitions but I've never personally put one to use on a porsche engine. I did have one equipped on a different turbocharged vehicle I owned in the past and it worked very well.
