Should I get a cold air intake tune?

I just got a cold air intake for my 05 wrangler, should I also get a ecu tune for it?

1. CAIs don't provide any noticeable improvement. They are used when the OEM airbox needs to be replaced due to space constraints.
2. The OEM ECU isn't easy to tune and unless you have a supercharger or turbocharger tuning won't provide any noticeable improvement.
 
Waste of money and then some. Unless you’re planning on a CNC ported big valve head and some long tube headers, you won’t gain any power whatsoever.

You can’t force more air into an engine that can’t handle it.

Probably get more gains by installing the decal that came with it. Chris nailed it on the head, as with any engine upgrades, it has to be a whole package.
 
A tune will help a lot with or without CAI. Flyin Ryan is who I would use unless you can do it yourself.

Do y'all know what a stock intake port flows? Would you know it is good or bad? IMO the cam is responsible for poor airflow than the head.
 
Update: Just installed it, and I gotta say I can definitely notice it hitting the redline faster...
The placebo effect is amazing.

A lot of what “ECU tunes” do is just change the throttle mapping to give the effect that you’ve got more power, when all you really have is less low end sensitivity. Even if it did “improve horsepower,” it had to come from somewhere, which is likely fuel consumption and parts wear.
 
yeah i'm not gonna lie, it could be placebo. But, I run straight pipes and now my exhaust is constantly poping and cracking so i consider it money well spent even if it didn't improve the power

If you’re obsessed with more power enough that you paid for a cold air intake and ECU tune on a tractor engine then put the exhaust back on, you make more power with it than without it. Road engines were designed to work with backpressure.

That “crackle” is also called overrun, and it’s just the sound of excess fuel being burnt (aka a waste).

At the end of the day though, as long as you’re happy.

You are thinking throttle by wire.
