More?,
more what?.
HP, MPG, drivibility.

The oem chips are as generic as they can make them and compromise emissions, and performance.

You'd get further faster by experimenting and learning with a stock engine, and then as you make mods edit your program to optimize performance.

You have to walk before you run.
Too often guys build a monster motor, then try to learn tuning, on the good engine. Which is a waste of engine life.

Not to mention drivibility, and mileage. Sometimes your driving does match what the oems do. however if your like me, I hate the stock calibrations. But, I've done enough of my own to get them the way I want them.

Once you've driven the perfect calibration, you'll be spoiled for life.

Doing a search with the phrase Final Answer might help you.
