My first dyno after the mods is this coming Sat at the Spring Fling in Dillsburg, Pa.
Stock dyno was 264hp I forget torque but I think it was high 400's
After adding the TST box and doing some intake and exhaust mods it dynoed 423/810 consistantly.
The trans started showing a little weakness here at 65,000 miles on three years of that 423hp. TC slips and shutters a little on highway and I don't like the stock 48RE behavior as it was. First and second not putting down the power and abrupt lockups in 3rd and 4th.
Now that the trans is done with the triple disk Goerend I feel like I have a totally different truck. Add the turbo, injectors and misc and I hope for 500-550 rwhp. I'll be satisfied with that. Lloyd at MidAtlanticDiesel.com did the selection on components for me based on what I was looking for..... good drivability, durability and great power.
