my first upgrade from stock and man am I impressed, easy install, video walks you through for dummies like me, wish i had done this years ago, fuel mileage wen't up along with the performance, first tank, 499.3 bye 23.6gallons, 21.16, 98 quad 4bye with 410 gears, auto , also installed new return line overflow valve and new fuel filter also, the speedo reads 60 when it's about 65 as I have tall 265, and the speedo is set for the 245 stock tire, so mileage is actually a lil better then i am doing the math on. thanks dually for the link to these guys this works very well, feels like I could do alot better with a different convertor though as the stocker can't pull it down where it pulls good till its in overdrive.

 

Did you also purchase their Killer Dowl Pin kit too? Same great instructions and a very complete kit! Enjoy your new HP!!!
