I did 249 laps in XFG and never bettered 1:35.91, so I'd be happy if I got near your time.
Couple of sets attached I used with keyboard. I hate oversteer, so not sure how they'll be. The one with time is a set I got from someone named Spikee, who could drive much faster than me, but I could drive with his set - just nowhere near as fast. Not sure about other set - I haven't driven that combination in years, but likely my hotlapping set.
I have other sets, some I was given when racing (sometimes I asked and got, and sometimes I got because people took pity) and they were all by people with great times and much, much better car control than I had, or even have now, and other sets were taken off Team Inferno's Setupgrid website.
If you want to try them, let me know, and I'll attach.
You could also try XFG sets for other track combinations, like KY2, SO4, etc. The gearing might not be exact for BL1, but maybe the handling will suit better, and you can always change gearing on the set that suits you best. If the tyres overheat too soon, pump them up, and if don't heat up enough, let some air out.
