I have a pte54 on my car and love it pretty good spool up on my combination.Istill have the d-5 converter but Ialso have alky and run my boost pretty high so with the tighter waste gate rod I have good spool up.I am running a huge homemade front mount I did not like the way it spool up with the stock intecooler. Awesome spool up with the front mount and max effort thumbwheel.I have had the turbo on my car for almost a year and it still feels tight as when I bought it.My trans. is about dead so no numbers as of yet.I run it on my g-tech and it run 13.2 at 114 mph at 19# of boost on street tires and the smell of clutches from the trans.
