Going to dyno the 6.4 Saturday

Ok guys, I'm going to dyno my 6.4 at Relentless Diesel this Saturday and I need some advice. I've never ran on a dyno with a diesel or an automatic, so how should I do it? I'm running the spartan 310 tune. I've heard to get it up to 65 so it wont down shift and then get on it. Does this sound right? I also heard not to worry about building boost. Any advice is appreciated.

65-70 MPH is good for the 310 tune. At that speed, it shouldn't downshift. If it does downshift due to load, bump the speed up higher until it doesn't downshift anymore. Just roll in to the throttle. You should see pretty close to the same amount of boost you do on the street.

you shouldnt be driving the truck, the shop should. But the above advice is good if you do, and BTW do not hit your brakes!!

We Might have to, I'm not sure if the dyno is a load dyno or not, the guys that are dynoing their trucks might have to hold the brake to build boost, if it's a load dyno then that shouldn't be necessary, correct me if I'm wrong but that is what I was told

Load dyno or not, you won't need to hold the brakes to load the turbo's on your truck up. You don't have a big single or a big set of compounds. These are fast spooling stock turbo's. If you have to hold the brakes to spool the turbo's, you shouldn't have your truck on the dyno in the first place.

Damn, forgot all about the dyno day up there. I will be at the Supercross event at Reliant in the Edge/MBRP booth, otherwise I would be there. I am very interested to see the numbers from the event.
