My experience with converter companies is that they can not predict how their finished units will perform. In the last 4 years I have filled out the forms for several major companies, and provided time slips, dyno sheets, and all the engine specs, everything they asked for. Not one of the companies spec'd the same size or type of converter, at over $1,000 I expect better than an educated guess. If the companies had it down to a science then I should get similar combinations from each company right? I have had several companies spec camshafts for example, and they almost always give me very similar choices. If you want the best performing converter be ready to buy and try several to get one that works with you combination. Just my experience.
