Bama Tune for a stock setup?

[Emt1581]

In this vid it looks as if all they added was a new cold air intake and then hooked the car up to a computer to tune it and ended up with 25+ extra horsepower. I always thought a super charger or turbo was needed to do a tune.

If not, is the Bama Tune the best for a near near/stock setup or is there a better option?

Anything about tuning a stock setup bad for the car?

Thanks

Looks like the tune alone got a 22HP increase, and adding the JTL brought it to a 30HP increase.

Most on this for that I read tend to stear away from American muscle and go toward Lund or another performance shop with a good rep

It doesn't appear anyone actually answered your question.


No, you don't only need a tune just for forced induction (turbos, superchargers). Modern cars almost always require a retune if you are modifying parts that change the flow of air and fuel. Things like a catback exhaust don't require tunes because you really aren't changing the exhaust flow enough. Turbo cars, NA cars once you touch the exhaust from the engine back, you will need a tune to either benifit from it or to eliminate sensors, ETC.

Adding intakes cause the MAF calibration to change because it's expecting X amount of air to pass through it but now with a larger intake that pulls more in, it's getting much more than it's programed for. Sometimes the computer tries to compensate by adding more fuel, etc which can cause issues.

For a stock car, they are restricted from factory. They are tuned to be reliable, meet regulations and to perform. In order to have a tune like that, you obviously are taking some things off the table. An aftermarket tune like Bama, Lund, AED, etc go in and modify those things and calibrate to become more responsive to fuel, removing some of the cushion the factory installed on the tune. Some aftermarket tunes provide better throttle mapping which makes the car feel faster. They will add more timing to give the power a bit more power through the low and mid range and sometimes you can even get a slight MPG increase.

Most sporty cars can usually see 20 to 50+ wheel horse power more just out of a tune.
