When looking for a compressor map for a T3/T4 I can't find any.I'm assuming that since i'm looking for a compressor map I should be looking at the T4(compressor) side of the turbo to corraspond to the map that is for that turbo

ExampleT3/T04e 60 Trim TurboThe map for this Turbo would be a T40E 60 Trim as seen here.

Am i Correct on this assumtion?

The compressor map will be for the T4, I think you are not using your terms absolutely correctly. A T3/T4 is a hybrid, it uses the T4 compressor mated to the turbine of a T3. This allows for you to use the fast spooling turbine from the T3 (which also has better import aftermarket support, but that is a debate of 'chicken or the egg'), but the higher flow of the T4. This in turn gets big horse on stock blocks because it is low boost. So, short answer made long: look for the compressor map for whatever T4 you are looking for.
