Constantly about a second or two off the pace, any tips?

I've jumped on the wheel about 3 weeks ago and managed to match my normal pace again in that time. However, i've found on 2016 whether im on the pad or wheel whenever i jump in an online game i'm usually 1-3 seconds off the pace. What am i doing wrong? I use manual gears, but have abs and traction on. Is it just more practice or is there a fundemental im missing out on? I can provide recordings of my laps if needed if that'll help.

Thanks
