Well when I talked to Coan I told them I wanted a convertor that is for a car that will make 550rwhp but I ended up making a ton less so the convertor is for a higher hp car and is tighter then I need it to be, had it been alot looser then it would be ok, it just locks up to fast and doesnt let the car get into boost before locking up. So I could take out the trans and send it to coan and get the correct one or just add a small shot to get the car rollin and then let the boost take over. The easier way was with the nitrous for now. When I yank the motor out this winter then I will get the correct convertor.
