Stock Truck
91 Octane
Stock the truck makes a modest 365whp and 440ft-lbs of torque. I installed the newly released COBB Tuning Accessport on their Off the shelf 91oct Stage 1 map. This map made 397whp and 514ft-lbs of torque. There were clearly gains to be had on 91oct.
I ended today on my own custom map at an astounding 434whp and 549ft-lbs of torque! That’s a gain of 69whp/109wtq over stock on **91 octane**!!! The truck is completely different. Throttle response is 10x better, and with COBB’s Dynamic Pedal Control the end user can further modify pedal feel to their liking!
I wasn’t able to add as much ethanol as I had wanted but got content up from E9 to E21. With that I made further adjustments and ended at 444whp 549wtq.
Needless to say, I’m impressed! A bone stock truck plus a tune. I expect another 20-30whp and better power up top with higher ethanol content. For now I’ll spend more time on the dyno and see how much more power I can squeeze out also continue to refine these calibration files.
I’d like to give a special thanks to Lance at Hammer Performance in El Paso. He let me spend the majority of the day on his dyno for my testing. He also has a ton of cool Raptor projects going! Special thanks to Joe for the help during the process!
Thanks for reading.

I’m confused as well, why would the stage 2 make less torque? Does that mean the stage 1 is too aggressive? Will you please give us insight into why the lower. Should I be worried about running the stage 1 tune?

Couple reasons:
I started the pills later in the RPM range, and I was a little bit more conservative this session down low because I didn’t want things to get out of hand trying to make more power.
I also had some high altitude things I had to work thru.
In total yesterday I did 38 pulls, didn’t get to test ethanol, and didn’t get to compare stock, stg1 ots, custom stg1, e20, stg 2 ots, custom stg2, and an ethanol blend. I ran out of time
I do plan on going back and doing an apples to apples comparison. My point in posting was that it made significant gains up top. I also did 6-7 pulls in a total of 2 min to see if I’d lose power like I did with a stock intercooler. No power loss at all!
The stage 1 maps I have a not too aggressive, thanks for asking that because I completely understand that question!
I will go back and do a comparison against all maps very soon!

Looks like I should have some 93 data on March 9th with the help of a member here!
What's the altitude above sea level there at the dyno facility?
SAE adds quite a bit to the forced induction numbers. Your improvements based off of the before and after runs are certainly legit as they're both run with the SAE corrections, but still the numbers you're getting on the 91 octane are not the same numbers that would be seen on the same tune at sea level or lower altitude using the SAE corrections.

Barometric pressure is 12.4, so ~4000ft.
Unfortunately there's nothing I can do about living at elevation. But like you said a 69whp gain is a 69whp gain whether I start at 100whp and end at 169whp, or 365whp and end at 434whp. And it's a dynojet, so numbers are what they are.
365whp out of a stock truck doesn't seem out of the ordinary, right? Using your logic I'd expect that same SAE to add quite a bit to baseline numbers (365whp) too.

Yes, the baro adds to all the runs. 12.4 is awfully low! I live right at sea level and most days are 14.6 and some at 14.8 with a high pressure area over us.
The DynoJet data display will show the correction factor as a decimal number as well, with 1.00 meaning no corrections and anything more or less is adding or subtracting percent. Many local dyno plots actually take away several percent due to the great air here.
Can you post the run conditions on each plot. It is in the DynoJet menu at the top of the screen. Go to Tools, Graph Options, Display, Display Conditions and it will show all the run data for those inquiring folks, like me.
edit: or better yet, send me the drf files and I'll look at it.

When I get back to the dyno I’ll get the file.
Also, I’m jealous of your sea level mod It’s not fair haha

Hello Goose! First of all I want to thank you for the COBB AP and the special sauce for my truck! It is like a different truck now! When logging, I noticed it will boost to 26.3psi, is this something i should be concerned with? I also notice a slight shutter in WOT. any suggestions?
OP

Hey man thanks for the kind words! I sent you a PM.
Boost levels can vary, even Cobb maps have a note for 23psi +/- 3psi. It’s normal.
As far as the stutter I’d check plugs. Seems to be quite common.
