TESTIMONIAL

Hello Mike,
I would like you to know the coan 9" max performance  
converter you spec.out for my car worked out great.
The car is driven to track 120 miles round trip to
track.              When driven on the street the converter has
no
excessive slipping from a stop, on track I foot brake to
3000 rpm and  It flashs to 5200 rpm .

Thanks Mike for all your help.
