iregardless of what rpm the converter is advertised..its gonna vary with different motor's, cam profiles etc..in order to properly place the launch chip you must find where the converter flashes ( actual flash)..it will flash more off the tranbreak..so i would recommned checking the flash point off the tranny break instead of foot break...
when you find your flash point then you want to place your chip anywhere from 1,000 to 800 rpm back from this point...this will give you the hardest launch and quickest 60 ft time...
if you leave past your flash point the car will slow down on the 60 ft..It will LOSE THAT SLING SHOT FEELING...
