If using 4 tyres of the same size you're stressing so much the belt and binding the transmission.
Regarding 0.8 gearing... Yesterday received mine gears and went to try at the track and a big smile was on mine face.... Sweeet! 2nd gear isn't no more sluggish (and now, I'm using a 5 tooth split - finding a suitable gearing for this weekend). Now is 21/60 and 26/53.
i was running about 1mm smaller in front..
the 0.8 modules work so well for everybody...mine is a 6 tooth split 20/59 and 26/53 as i needed more acceleration for 1st gear in the tight infield
