Lee,
Just go ahead and fork over the extra cash
for an AEM EMS and be done with it. The AEM
is not going to cost much more at all than the
late model PMS & datalogging option....
Depending on who you buy it from you will get
a base tune with the AEM to start from.
If you need a recommendation for the AEM let me know.
Unless of course you are just looking for something
that all you do not need a laptop to tune with....
