this just doesnt add up. I run high 13s at 99 how can you pull a 15 flat at 99. the mustang MUST have been an auto and MUST have been a POS. Sure it looks nice but to lose to you, a POS. 15 flat sounds about right for the mustang but the nissan maybe 17.50s in good weather . With only bumped timing and an air filter, come on be for real.
