I can't imanine that you can get the same kind of fuel and spark control and logging and data out on a stock ecu that you can get our of something llike the FAST system.

But if $ is an issue, run stock until you decide you need more control or more data out.

Then when you need more than your stock setup gives you, look around at what the faster cars in your class are running, and go for that.

My Opinion. I never ran a stock ECU in Class, Your mileage may vary.
