DDMWorks Intake Slower?

[m3t4lm4n222]

So I installed a DDMWorks intake to my 2014 Sonic with the 1.4 Turbo. I got it fully installed, car seemed fine, maybe a little slower, but I assumed it needed time to simply tune itself. It's been about 400 miles since it was installed and it seems as if the Sonic is actually slower than it was with the stock airbox. Any ideas why this may be?

I appreciate the help!

Are you tuned?

If this is the same question that was asked a while ago by the same person in the wrong section, it has been answered already and the car was on a stock program.

In case this is a different person, without a tune the ECM will detune the engine to maintain stock power levels no matter what parts you throw at it. It may seem slower for several reasons. The power could be peaking earlier, depending on what filter you are using the MAF readings and fuel trims could be way off and the ECM is struggling to maintain proper fuel trims and air/fuel ratios, something was done wrong on install and you have an air leak, or for some reason the ECM detuned to less than stock power level.

If you want to reset fuel trims unplug your battery and turn the car on. It'll drive like the intake is supposed to, then the car will decrease it to stock levels

how do you turn the car on with the battery unplugged?

Resetting the trims will do no good if the intake or filter are causing the MAF readings to be incorrect. If its wrong due to airflow being different from the stock system then resetting the trims will do no good.

I've uninstalled and re-installed the Intake just to be sure, there's nothing wrong with the installation.

I'm not trying to say it doesn't feel faster, I am trying to say that it feels slower with the intake. Could it potentially be due to the engine sucking in more hot air than it does with the stock airbox? Any idea if purchasing and installing the heat shield would legitimately help?

Feels slower and is slower are two different things. Without a tune the ECM in your car will strive for stock power levels. Even if it is sucking in hot air, the difference in temperature compared to a stock intake should be minimal by the time it gets to the manifold. Now, if you are heat soaking the intercooler by making a bunch of hard runs then it might not be effective and cause the ECM to dumb down the engine to reduce power and save it.

My guess is still that the ECM is dumbing down to stock power levels and you are perceiving that as being slower than stock.
