Serge with race gas and your mods you must be making well over 500hp.
On that run i left it in D and was on a full tank of 91 octane gas and yes that would of been a killer photo finish.
I will have tune ready by next event and will run both setups (stock/tune) so we can see the real difference. I may also have a new exhaust setup by then.
can't wait....great event!
