Just to be on the safe side I think I'm going to add a V&H fuel Pack or a Power Commander Because I can't really tell if is going to be Running to Lean and I don't want to Blow it up. Some say that the stock Ecm on the 2011 will accept the Change's I made, But I don't want to take a chance.

I for one believe that ALL hd's are Too Lean , That said , the HD have their bikes set at Above the 14 AFR level which makes the Hd exhaust okayed by the EPA but CLOSE to running Lean Enough to do damage to the engine.. HEAT and LEAN go hand and hand... TBones has a good post on this and is well said and easy to understand. I'll try to get it here.. GOT IT****************

Re: oil cooler fan or engine fan?
*****************
Stock Delphi Ignition systems are setup to run the AFR at 14.7... They have what's called parade mode, when the motor gets too hot, it will reduce the AFR to 12.5 at idle, anything over idle and it reverts back to 14.7 AFR... One of the best things you can do to lower your engine temps is to get a good tuner that gets your AFR back to where it's suppose to be for internal combusion engines...
The company had to run the motors at 14.7 to meet the EPA exhaust emission standard... 14.7 is right at the limit (lean) before engine damage will occur... Internal combusion engines run their best with the AFR running between 12.5 and 13, you get the most power and your motor will run cooler, you'll take a hit on the gas mileage but with the aftermarket tuners you can adjust your AFR to run in the 14.0 range in the cruise rpm range that will get you the best mpg... Fans are certainly good and will help but if you get the AFR's correct, you won't necessarily need a fan to help cool your motor unless your riding in outside temperatures over 105 degrees, then even with a fan the motor can get pretty hot especially at idle with no wind going over the fins...
