Yes, well if you're tuning a motor...ET aint a lot of use...too many variables, unless the chassis is well sorted.
BTW - I ran the kerb weight of a 2013 SRT 300 plus driver (4360lbs) and a known MPH of 110mph belonging to a guy I know - I put that thru Wallace...
474 Engine HP - So its pretty close!!
