lost power need advice
 

Hi guys I put in a edge comp a couple months back along with a raptor 150 and all has been great untill the other day I was pulling my work trailer and noticed I was still set on 5 so I adjusted it to 2 on the fly and it hesitated and ever since that I've lost about half my power. Lift pump seems to be working just fine fuel gage is still reading 19 like it has sense day 1. Also installed a big banks wastegate when I did everything else. Ordered a code reader but hasn't arrived yet. Does anyone have any ideas what may be going on.

To check codes without a scanner, turn the key on off on off on and any codes will show in the odometer.

loss power
 

So thought maybe it was a boost problem so last night I pulled the tubo function tested my banks wastgate and it seemed fine I put 2 turns on to up my boost some and today back to normal running down the highway like a raped ape. Check engine light however remains to be on. I do kind of feel like it's a coincidence that it's running good I don't feel that I have found the actual problem kind of Clueless
