tertiary substrate favours elimination and among substitution SN1 .......BUT IN CSE OF TERTBUTYL CHLORIDE WITH 80% ALCOHOL AT 298K ,83%PRODUCTS ARE SN1 AND 17% ARE OF E1......WHY??????????????

1see dude, unlike SN2 and E2 separation , differentiating b/w SN1 and E1 is a bit difficult. this is because SN1 and E1 hv the same rate determining step i.e. dissosiation of alkyl halide and both hv same substrate reactivity order : 30>20>10. thus the only way to differentiate is temperature .SN1 reaction takes place at lower temperatures while E1 at higher temperatures.
this reaction takes place at just above room temperature ; thats why SN1 reaction dominates over E1.
competetion b/w substitution and elimination reactions is a very important concept, i believe.
