Ok guys. The time has finally come. The ol stock Allison is on her last leg. I'm runnin somewhere in the high 400's with my efi tune. I've been milkin' her out since i got efi last summer but she just wont hold that kinda hp anymore. I can perty much limp my tranny on command haha! But anyway here's my problem. The only internet access i have right now is via my phone and so i cant do much research on here so that's why i need some advice. I was gonna go with the sc stage v with an ats autopilot but after i talked to my guy he said it would be $7600 all together. That's just a bit too much for my price range? So ehat do y'all suggest? do a stage IV rebuild? i'll be sled pullin more this summer and id like to start crankin out more hp after i get my fass. I wanna keep this as close to $5000 as possible. Gotta figure it out within the next week! Any input would be awesome!
