ok guys so today I finally took my 55 to get some pulls in on a dyno jet .my results where bad I believe I only put down 424rwh and 476tq.and the sad part about it is that a stock 55 is putting around the same as me ..my set up is
83mm sc pulley
Kleemann headers mid leinghts(straight back no cats ,2dary cats replaced with xpipe,resonator and no mufflers)
FTP HE
colder sparks
Split cooling
And eurocharged tune to support the mods
Well I was told that my 55 was way to rich and that my tune was way off .so yeah what are u guys putting down ?I thought I would be around 470rwh with all my mods

It's a little rich , Jerry can lean it out a little and get you another 20 or so hp. We're you heat soaking? Did you let the car cool down a little before running it?

Yeah I'm sure jerry can help me out he's grate .just thought I would share it just to get it out my chest lol
Yeah bro by the time they strapped the car and got everything set up I say it was off for about 1hr or so ..that's enough time for it to cool down ..second pull we took off the kn filters and it made a difference weird

Different dynos bro. You have a tune already , right? If so, even if he leans it out a bit I don't see an extra 50hp. You will probably get 20hp more if he leans it out a bit

With headers, blower pulley and tune, you should be right at 500rwhp or slightly more on a dynojet.

Can you data log to see what your iats are?
Can you post a better pic of the air fuel graph, it looks to be dumping into the 10s or less. That can be the ecu washing the cylinders due to high temps or the tune needs to be leaned out.
What gear did the dynojet operator do the pull in?
Is that dynojet at 224?

You have a nice simple combo that makes hp, it just needs to be tweaked.

Let me know on my above questions

Was the car tuned on a dyno before and you were just like hey wonder what my numbers on a DJ would be vs the dyno dynamics you were tuned on?? I'm sure my numbers below would look nuts on DJ.

Need to know some details...

What gear was it done in? 3rd is ideal for a near stock car. No need to push it by doing 4th gear pulls.

What were IAT's during the runs? I'm commanding 11.x, so I'm sure they were 160+ when it went to the 10's.

So it's a box tune and EC has never tuned while on the dyno?? If that's the case then the file would be rich to be safe. That being said you got on a dyno and should have had them remote tune after a baseline.

I'm thinking it was 4th gear
Really wouldn't know about the other stuff I went to them only reason was because they are one of the good dyno shops here in sd..
So should I go back to them and tell them ??
Thanks

If it was a 4th gear pull, you were heat soaking. Your iats were through the roof. Dyno again in 3rd gear.

looks like you lost tach signal too did he hook it to the coil pack that usually works the best. do not worry about dyno numbers this time of year you should know and be looking at your act i really do not think most know the damage high air charge temps can do time after time.

Yeah, it is pegged into the 10s for air fuel around 5000rpms. I would check your iats on a 3rd and 4th gear pull. Your IC pump maybe on its way out, causing fuel dump.

#rd gear pull is the only way when on the dyno, and btw, a Dynojet is not a heartbreaker lol. Dynamics and Mustang Dyno's are.
