Back again for another problem query. Noticed twice today that on start up my exhaust did a little pop that I haven’t heard before on the previous days on e85 or entirely of running petrol. 1st pop was on a coldstart but second one wasn’t so what’s going on there?

I believe my tune has modified the start up to eliminate e85 cold start cranking, is that what these little pops are?

Coldstart only revs up to around 1.3k. The pop was the same as a gearshift backfire. Wouldn’t have questioned it had this happened every other cold start up since the e85 switch
