I just have a quick question. Will installing the AEM intake on a bone-stock X cause enough enleanment to require a professional tune? Is it safe to run the intake without tuning it?

 

I think you should be good as long as you don't raise your boost.

 

Your Maf scaling will be off.

I ran a apexi power intake without a tune for a while and was ok, but i did not beat on my car. A tune will revise the scaling and provide for accurate airflow so you can realize power gains. I would get a cat back and then a tune.

 

So...........intake with no increase in boost and everything else stock is ok with no tune?

Here is their map which support GSR and MR, Also you will see they have map for AEM Intake!

 

Yes, you're fine.

 

The tune should come before the intake and when it does, you won't even need or want the intake.

The AEM intake does not add power once the car is tuned.

 

9 times out of 10 the scaling will be "off" when swapping MAF housings. A lot of the time, you may see more power/torque as it skews it lean. Since it will likely see less air moving by it, the calculated load sites hit will now be lower. This means that your ignition will be more advance too.

This works well sometimes until the boost gets turned up or a higher flowing turbo is added. Unfortunately, skewing it lean for open loop operation may have a positive affect, but your closed loop fueling will suffer as the ECU is attempting to "add" fuel to keep it stoich while lugging around. A lot of times depending on the ECU manfacturer, a learned fuel value will be applied after enough time for the data to be sampled and the ECU will later begin adding fuel back in.

So yes, a good tune will normally be necessary.

 

Thanks for the replies everyone.

 

I don't mean to thread jack but i got the harmon motive intake and was wondering if it was ok run it on my car. I have the wastegate tightend 1 1/2 turns in

 

If the MAF housing has been changed then the same would apply from my post above.
