yeah thats not too bad, TBH my 197 isnt as bad as people make out, between me giving it some beans and the missus driving like a nun we average 29-29.8 ish, sometimes goes down to 28's when iv had it for a few miles . saw 34 when I took it on run to chesterfield on all A/M roads once!
They are possibly as different as the 182's were then!
My old one used to get 38-40 at all times (it wasnt driven any differently to the 197) yet most seemed to report early to mid 30's!
29 is a fair bit more than im seeing! I do only use the best juice form Shell (or BP as a substitute) too so i cant figure why its so low really!
