SAE CORRECTED is the option you want to use. It's much closer to the actual output. Uncorrected has a tendency to inflate power numbers a bit. It's situational, though. Sometimes uncorrected will produce a lower number. There's a lot of factors that go into it, but that's why Corrected is more accurate.

UNCORRECTED:
It is just that . Uncorrected. No Corrections factors and no set parameters.

SAE:
"SAE (Society of Automotive Engineers), USA. Power is corrected to reference conditions of 29.23 InHg (99 kPa) of dry air and 77 F (25°C). This SAE standard requires a correction for friction torque.

STD:
STD is Another power correction standard determined by the SAE. Power is corrected to reference conditions of 29.92 InHg (103.3 kPa) of dry air and 60 F (15.5°C). Because the reference conditions include higher pressure and cooler air than the SAE standard, these corrected power numbers will always be about 4 % higher than the SAE power numbers. Friction torque is handled in the same way as in the SAE standard."

Not to play the bad guy here, but........
Your gains are pretty much what I expected. No real hp difference under 4500rpm, where the engine doesn't need any extra flow. What the dyno shows and what actually happens in real life are also not always the same. No matter how it might "feel" now, 6hp 6ft/lbs at the wheels is 6hp 6ft/lbs at the wheels, not enough to make it any quicker in any noticeable way in a test like a timed 1/4 drag, especially in such a heavy vehicle. Worth the cost? I guess it depends on the individual.
*BUT, give your Jeep a thousand miles or so to really learn the new parameters, and dyno it at the same place again. See what numbers you get. I assume you didn't reset the factory computer when you swapped the parts?
Either way, good on you for doing the actual work here.

Has anyone confirmed an increase in MPG w/CAI?

I done have a true cai but I have a spectra brand from O'Ralleys and it seemed to help a little. Maybe 0.5 - 1.5 mpg. And a little more power. Not much though.

Im trying like hell to stay off the gas long enough to give you guys an MPG update.

Stay tuned.

How about you guys dyno the y-pipe by itself?

The Ypipe as I understand it is more for the relocation of the pipes, for lifted jeeps rather than a boost in performance.

The drive shaft is very close to the cross pipe on the stock jk, The Afe y-pipe makes more space.

I don't care about power gained, I am more concerned about power lost.

My Jeep is definatly faster than before, not possible that any of these mods cost me any power.

Are you guys getting a lot of intake noise with the AFE setup??
Does the wall and rubber meet up with the Hood??


I'm running a AFE on our 06 Duramax Diesel and like that setup
but it's more enclosed and quiet.

Not looking for additional noise just better airflow.

Thanks guys.

At this moment I have no desire to upgrade to exhaust/intake. I already have the afe y pipe, I just wanna see a dyno run stock and then with just the y pipe. Again, I don't care about power gained I only care about power lost.

Yes, my response to that was that there is definatly no power lost.

I drive the truck now, and I drove it before. It had more power when it was dyno'd, AND when we dyno'd the truck the new parts were a surprise to the cpu. As I drive it now I can feel its more powerful. If you see the air flow charts, you could see that the cpu was altering the air flow in each run. There is no possiblility of a power loss.

It takes more than 3 runs for the cpu to realize what was done to it and for it to become optimal.

I think they are just messing with you. Ignore them

Have you guys not heard of the butt dyno?? You can tell when your ride is stronger.

Ever driven a force induction machine on a cool dense night?? Feels stronger,, and thats not a 35 hp gain,, its maybe a few,, and you can tell a difference.

I'm not messing with him. Forget the exhaust and the intake.....

I want to know if the y pipe either loses power or stays the same. That's it! Not with the exhaust or with intake it makes power, not it "feels" the same. I want someone to dyno a stock jeep, then install the y pipe and dyno again. I hope someone in this thread understands this.

^ basically what he's asking is does the Y pipe alone help or not. IMO it does senses it will help with the flow. More flow means more power and more mpg. Correct me if I'm wrong please.

JMO, the Y-pipe alone shouldn't effect hp, it is a slightly different shape from oe to allow the driveshaft more clearance.

The ypipe is not designed to add horsepower or torque, it's just to relocate the pipe so it dosent touch the driveshaft.

It is the same diameter as the stock ypipe.

I Also didnt install it in my truck when the engineer at AFE told me that because my truck is not lifted.

Just a quick question, did you monitor the afr? Most modern engines have a set afr in the ecm. The ecm can make slight adjustments on it's own, but .... Adding a free flowing intake and a free flowing exhaust might be more than the ecm can handle, thus running a lean condition. That is why in most of the cases the ecm is remapped to accommodate these changes. While it may not be harmful at first, running excessively lean builds engine heat which can cause premature failure. As we all know, a little extra fuel will actually help cool the combustion chamber from a lean condition, and will help you gain some hp and torque. Some might add that running a little richer will help the mileage as the motor isn't working so hard to make power.

If I am not mistaken I think that is exactly his point ( why he is not concerned with gaining power but losing it). The concern is that if you swap out the factory pipe there is the possibility of power loss due to the design properties of the new pipe.I may be off base but that's how I originally interpreted the question...since you did not utilize the pipe I suppose he will need to look elsewhere for an answer.

I did do the AFR, If you want to tell me specificly how you want to see it, ill post the chart. I have 3 runs of each - stock - intake - intake and exhaust.

Tell me the format you want and put it up.

Thank you!!! I didn't think it was too hard to understand.
