mines running greys lived mapped and tuned by MSD pushing out close on 400 bhp, if i stick a tenner in and nail the arse off it i'll probably get 12 to 18 miles out of it, on the other hand i went to newquay in it which is nearly 300 miles from where i live, filled it up 55 quid and it got there on 55 quid with 2 kids misses and luggage at a steady 60 to 100 mph........not bad considering.......
