Injector Balance rates effected by low compression???

[MAXX IT OUT]

So i have been having issues with my number 6 injectors balance rate going up and down, but general being around 4, before and after changing to new injectors. Its also blowing a fair bit of white smoke and runs a bit rough/stumbles the engine is cold, even at 70 degrees. I haven't gone to crazy trying to figure it out since I have been gone out of state for work and the truck runs fine once it warms up. Is there a effect from compression on how the injector functions/ reads? I can't to a compression test currently and hopeing for some food for thought or information. Any Ideas?

yes, low compression will affect balance rate's. been there on my old 02 lol

Balance rates are a measure of how well each cylinder is performing in relation to the other cylinders in the engine. If one cylinder is significantly lower on compression than the others, it will have a high + balance rate.

That confirms my suspicion, now to figure if its a bent rod or cylinder head issue.

Yep when I lifted the injector on my truck the rates went to shit. Started at 2 and slowly crept up to 12 while idling.

When I bent a pushrod and my valve was hung open my balance rate on that cylinder was 15
