1badTTA (whoever you are), I'm the one who said that about my converter. I think it would be better if I could shift at 5500-6000 instead of 5000. I wanted a 3000 stall but Yank sent me a 3200 or so stall because they thought "it would spool better without having to sit at high boost on the line for very long" (and that's after me sending back my first converter twice, and a total of about 9 months after my card was charged with no Yank in my car). My biggest complaint with Yank is the way they don't communicate and do what they think is best, unilaterally. I'm still running that converter because 1, I have it installed, and 2, I don't want to spend more $$$. I plan to go to better heads and a cam sometime soon, so will be turning more rpms, and then I'll see how it works. I do regret not getting a PTS 9/11, and may wind up with one eventually, but I had heard good things about the Yanks and wanted to try something new.
