Not sure they belong here, but here goes...

Jim Kartalamakis ranks the 75's Twin Spark cams as a 9 in performance rank.

Why do so many owners replace them? To me unless someone is going for some really serious HP, that sounds pretty darn good and - might be wrong - should work fine on a slightly-tweaked TS such as going up in compression. Also it is my understanding that the VVT is to add low down torque - which is what I'd like.

While I don't see myself ever dealing with an aftermarket ECU, has anyone who uses a Mac laptop with Windows used it to dial in an aftermarket ECU? If so, I'd be curious as to what model of Mac and which Windows program and number you're using?

The tuning app will be different for almost every ECU.
it is not like there is one program that works with all the ECUs out there. They each have there own app .

slyalfa, are you saying that each of the manufacturer's of aftermarket ECU will work only on a specific Window's platform?
