Torque app injector rates

So got the torque app to work right. Here aee my rates

Drive:1369271916362.jpg
Seems number 8 is bad. The numbers were fluctuating so i was snapping screenshots. I dont know much about injector rates. Are the negatives bad?

We're these taken at operating temperature? Spec is +/- 4.

By the way take them in park.

I'd run some injector cleaner through several tanks of fuel, and keep monitoring them for improvement.

Just in case heres the sites DIY for injector cleaning:

Would you say the torque app is accurate? Or should I have it tested with a different system?
