I just got back from Unlimited Motorsports here in CT and I'm pleased with the results. My truck is all stock except for the 5" exhaust, no cat about 1400 miles on the truck. Did 2 pulls and ended up with 271 rwhp and 534 rwtq on the last pull. The first pull was 268 rwhp and 529 rwtq. I wish I had a dyno graph to show you guys but the printout I got had no torque graph, I can tell you that the torque curve was totally flat throughout the entire rpm range.
Does anyone know if there is a way to lock the converter at about 1000 rpms and get it to not downshift for the dyno. Every time he did a pull it would drop to 2nd or 3rd and then shift. Let me know what you think. And by the way I got a Ramifier and triple gauges going in tomorrow

Good results. Was that on a Dynojet? Your numbers are very close to the ones we get on Dynojets consistantly.

Lock up like you want will require a hard wire lock up switch.

Let us know how the pressure box works for you.

Great numbers!

With the 48RE, you should put it in Tow/Haul mode, go thru the gears until it locks in 3rd, somewhere around 50 to 55 mph, then let the rpm drop to about 1350, then roll on the throttle to the floor, don't immediately floor the pedal, it will down shift, but if you roll on it, and have the pedal to the floor in about 2 seconds, the 48RE will stay locked up.

What kind of Dyno were you on? Did you run locked up in OD? If so, you would not get accurate results. Higher results but not accurate.

Both of the passes were in od with the converter locked and it was a dynojet. The mph on the graph was around 100 or 110. Can anyone point me in the direction of where I could find some wiring diagrams to make a lockup switch. The guy I am purchasing the ramifier told me that it did pressure and timing but I won't know for sure until tomorrow.
