RG M8 Turbo Bottom End Response

the cr number is the number that effects when the secondary injectors comes on.
like krafty mike earlier stated, you want them coming on in the low to mid 90's

CR 13

So just checked my CR, it was set to 13. That is way way way to low right? Secondaries would be coming on at like 2 pounds of boost. Shouldn't the CR be about 30-40... My Os is 20, should I adjust that???

30 worked for me with the same kit. Secondaries should then come on at about 6.7 psi. The 2008 original CR setting from BD was 13 & there is not enough airflow for the extra fuel from the secondaries at a CR that low (~2.8psi) & mine would bog terrible. Looks like you found your problem.

I left my OS set at 20.

sounds like you found the problem, im sure each kit/sled is a little different, change your cr to 30 like matt159 said, run the sled and check the stat screen on the bd box then keep resetting it after each check and get the duty cycle where you want it.

good luck.

Can anyone tell me what the "OS" number do??

OS is the initial amount of fuel the injectors flow. I have been told to pay attention when adjusting this as it will affect the entire fuel curve.
