An It seems like im not getting a lot of out the upgrade dosent seem faster than it should be.

My upgrades on my bike:
-DK Customs HiFlow-587 Air Cleaner
-Vance and hines exhaust
-NRHS Sportster 883 to 1250 Upgrade Conversion Kit

Anyone out there have the same bike and same engine conversion?? if so do you have the tune that you use on your bike? that you could email me?

or if anyone is willing to help me understand how to use the power vision better.

Welcome to the forum!

There are a few variables to the concerns you mention-

V&H exhaust is prone to popping, regardless of 883, 1200 or 1250. You can reduce/eliminate it by using Thunder Torque Inserts, and the added benefit is more low & mid range power.

Regarding overall power increase from the 1250 conversion...have you finished your break-in period yet?

Did you upgrade the clutch? As a rule the clutch that comes with the 883's cannot handle the power of the 1250 conversion, and when you go to accelerate you will not feel most of the extra power because it is being lost in clutch slippage. Energy One clutches and clutch springs will make a huge difference in the power you feel. Here's a link to them. EO Clutch

Regarding the Power Vision, there are tons of good vids on how to do a basic auto tune on Youtube. You can see one of them right

.

I have done a very similar upgrade to my 883 and it has all the power I will ever want.

Below is a vid of us playing around a bit with the power outside the shop.

Besides the TTI's and a stronger than stock clutch, After your break-in is done, I would recommend you doing some auto-tunes per the video above.

If you still are not happy with the power, give me a call or send an email and I can share with you the tune I'm using in mine, and we can chat a bit and see if we can identify what may be the issue.
