Tuning 2.4L LE5

Modifying the intake will throw a code. You have to change the acceptable MAF sensor range in HPTuners to alleviate that. The point repairman54 is making is that there isn't much to be gained with a "performance" intake on this engine, and one that isn't sealed properly from hot air will make the car slower than stock.

HPTuners is not for the faint of heart. It's an incredibly complex interface that expects you to understand what you're changing. It took me a couple years to learn how to use it somewhat extensively. Making mistakes can literally break the car, and you have to constantly keep that in mind when trying new things.

Feel free to ask me any HPTuners questions.

I completely agree with everything you are saying. I am going to end up buying an HP Tuners unit here soon for my.car because I have a buddy with an old Cobalt with a supercharger with the LSJ? engine. We planned on taking the time and switching over the components such as the intake header, throttle body. Pulley brackets and fabricate what we have too. It's not really a project of "want a fast car" it's more like "supercharge the frigging Malibu because why not". And I am seriously considering doing all of this my only problem is I am in Michigan where I can't seem to find a Dyno or anyone willing to tune the car near me. So I am willing to learn and do it all myself for the fun of it and there is nothing like doing it all yourself. Really I just want to have fun with this car. Because I can. And I understand that a cold air intake would be a bad idea because of the heat. I am just wondering what goes into the tuning process. I'm not really looking for answers to what needs to change. Buy WHY it needs to change.

Thanks for your time replying though. I appreciate the feedback.
