Message essentially be a waste of your money. The ECU programs I provide for the non-turbo will get you within 1-2 horsepower of what you can achieve safely with the ZEMulator.

The reason for going to the ZEM with the twinturbo is due to the fact that installing larger injectors, dual intakes, and other components that allow the system to move quantities of air surpassing over 2X the stock flowrate, will inherently amplify the inaccuracies of the ECU to control the engine. The more power you produce, the more "character" you get out of the vehicle... i.e., a program that works flawlessly for one high-HP Z32 will not necessarily properly fit one with identical modifications.

In short, if you have larger than 555cc injectors, it is best to move towards an aftermarket EFI system. Be that AEM, ZEMulator, or some other variant, this holds true given that the potential for variations in A/F mixtures, timing advance, etc are significantly greater than when producing lesser power levels.
