RDT is the Roush tool used to lay down their tune & it needs to know the correct gear ratio as well.
I guess I will have to ask the shop that put in the tune but I told him I had 3.31 gear just installed.

Like I said in earlier post same car as mine there with 373 gears still made under 600 hp with the phase 2 upgrade.

Is it a Mustang dyno??
Or a dyno jet?

My phase 1 (670hp kit) with Lund tune only put down 568/469 it was on a DynoJet @90 Degrees. Just upgraded to a 79 pulley/BAP and Colder plugs (basically a phase 2). Will be going to Dyno next weekend to see if it made a difference.

Ok, so when I had phase 1 installed (670hp calibration), I put down 601rwhp and 500rwtq at the shop that installed it for me.

I just finished dyno'ing with some other guys on Phase 2 + Lund + VMP heat exchanger and only made 593rwhp and 519rwtq. The guys warned me before hand though that this shop's dyno was pretty tight when it came to numbers, so to expect less than I've seen on previous dyno.

I'm 100% positive that I gained much more power after phase 2, so I'm blaming the dynos here. I'm going back to the shop that did the install for me soon and I'm going to dyno again. I'm guessing I'll probably make 660-675rwhp on his dyno.

I hate all this craziness between different dynos and different numbers. Everyone I went with today made less numbers than they had previously reported from other dyno sessions.

I'm also highly interested in upgrading what I have now...

I'm guessing you can use the sct tuner vs the Nguage? Do you find yourself using that guage for anything else except loading the tune?
Yup, I use it to show the RPMs, speed, throttle position (not sure why), and engine coolant temp. there's more parameters but I'm not monitoring them.

Yea 75 rwp from one dyno to the other is super stupid. It sure makes it hard to see if the mods you are making on the car are actually making you more power unless you use the same dyno or go to the track every time.

I just bought the Ken jonnes remote tune and the sct so we will see how it goes.

CJPony Parts ran theirs on a DynoJet after they did the install on their '15 PP project car.
This was back when the kit was just released and rated @ 627hp.

They pulled 555/479, but it was winter & amb. temps were < 40F & 18% humidity.

Roush said that they are aware of it and are working on an update. They said to check back with them in a couple of weeks to see if it is available.

I Have Just Decided To Go With A Ken B Jonnes Tune.

I Will Let Everyone Know How It Goes.

Nice! Glad to hear the real numbers I probably should have been making, lol. Can't wait to see what you get next weekend man.

Going To Put It On Different Dyno Not A Mustang Dyno And See What It Makes.

The Torque Numbers From What I Have Seen Look Ok But The Hp Numbers Just Look Really Low.

Its Just Weird The Car Stopped Making Power At 6700 Rpms On This Dyno And Still Was Going Straight Up On The Hp At After 7K On The Last Dyno Before Headers And Throttle Body.
