Bigger Injectors and Timing

[BothellDiesel]

I upgraded to 90hp injectors last week, prior tips were 50 hp. The truck idles even smoother (surprising but great) but now I have a slight shake or shimmy at 1700rpm's - 2000rpm's. I was told it could be a timing issue, or just the added hp that causes a little more engine rumble. What are some thoughts on what that shimmy/shake could be? Am I just overreacting. You can see in my sig that all I have is a Superchips on performance level. Truck drives and sounds great other than the shimmy.

I've been trying out a Smarty for a couple days now. I believe mine was set up for injectors and turbo. I tried running the added timing with the stock injectors, and I got a hesitation as well. When I tried the truck out today with the 90 injectors, it ran smooth. What I'm getting at is yes, I can see where timing can make a difference when you change injectors.

Reprogrammed truck with Tow power level. The shake is gone for the most part
