I know a lot of guys who have supercharged and turbocharged the V6, and made about 350hp or so, and snapped that stock 7.5" rear like a twig. I would’ve prob bought an 8.8 out of a GT and swapped it on, for the cost of opening up the diff, and installing everything, probably would’ve been a bit more, but cheaper in the long run. im not looking anything like that really, just the 4:10’s maybe a cam over the summer and all the bolt ons, 350 is outta my reach. But an 8.8 has definiatly crossed my mind once or twice, but right now i think its unneccesary. thanks everyone for the imput [rmpoutlet.com](http://rmpoutlet.com) sells a programmer plus underdrive pullies for like 400 and the programmer will fix the gear and speedo problem --- _[View the full topic](https://forums.speedlife.net/t/new-gears-messed-up-speedometer/188290)._
