Exactly what you should be getting !
Since you are getting the "2nd gear shift" wheelies on a 10k powershift, your top end fueling MUST be correct - or very close to it..
Not many of us have experienced the 2nd gear shift wheelie - Such performance is only possible with a correctly fueled and modded stockbore, and a good rider.. Congrats to you..
Now... That Barker exhaust (with stock cam timings, lidless airbox, and proper fueling) could quite possibly create 25+ HP KLX's.. It only takes 23.75 hp to pull the 2nd gear shift wheelies..
So, given the above, how did you "setup" your EJK ?
We will need all the tiny details about how your EJK is set up... For all of us that have (or will have) EFI KLX's...
Also it's very important to know - Normally, without the MCM, your powerband should be weak (weaker than when stock) below 5500-6000 rpm and "Raped Ape" above that, all the way to 10.5 k..
Is this the case ?

Do you think I’d get similar results with the EJK installed on ‘18 KLX250 in Colorado riding at elevations between 5000’ to 12,000’ ?

Will you see the same power at 5k plus alts as Kris250 - no.
Will you see quite a bit more power than you have now - yes.
What is unknown is how/whether the EJK has an effect on the ECM altitude sensing. This would be a call to EJK to verify that the unit does not defeat altitude based fueling adjustments..

I spoke with EJK today. Their system operates on top of the stock system, and adjustments for elevation changes will not be adversely affected. The stock EFI system will still adjust for elevation cahnges. The EJK system currently comes with an O2 sensor bypass. This will be the case through the end of the month 10/31/18 at which time the Enviro Feds are making them remove those from packaging. EJK is also the dealer for Muzzy exhaust systems. They cut me a package deal for a full Muzzy exhaust with the EJK controller. I’m excited to make the mods and add some power to my KLX250!

I think they’ll be able to continue to provide the EJK controllers, but not with an O2 sensor bypass included. Do you know of other resources to buy an O2 sensor bypass? Maybe EJK can suggest alternate sources for O2 sensor bypass options

I don’t know that they go bad, but good point though. I wil call them and inquire. I’ll also inquire about other aftermarket O2 sensor sources. I think they’ll be available as components through various sources moving forward.
Are yu still loving the results of your EJK, air/exhaust mods? Any issues that I should anticipate?

Yes I do! No issues at all one of the best running motor I’ve had yet. Today I sat back further on the seat and power shifted to second instence 10:00 wheelie held it and shifted to third. Pretty impressive for a little bike.
i was thinking about 13 tooth sprocket for better acceleration and 3rd gear wheelies
