Went and did a few pulls today. Quite satisfied considering that IAT were @ 110 degrees during the pulls.

The photo below is a jpeg of the sheet I was given, but it was in STD. 389whp and 558wtq



They also emailed me the run files and i attempted to use winpep7 to create a graph of the 3 runs but couldn't get HP and TQ together to work. These numbers below are corrected for the conditions.



The 389 STD whp becomes 382 SAE whp for the test conditions. Once again, not too shabby. THANKS ERICK!

That torque would be awesome for towing, impressive. I might have to do some more modds

Its definitely a blast to drive!

I forgot to mention, the runs were done in 3rd gear with the transmission in manual mode. whacked the throttle @ 1800RPM and started the pull. Lifted just before 6K indicated which apparently was just past 6K RPM on the graph. I'm pretty sure cooler temps would have only helped!

What mods do you have on this truck? Those are some impressive numbers! I also have a 13 lariat eb myself, been looking to start performance mods.

Thanks ecopat. On the app on my phone you can't see sig's.

Is it me or does the torque seem a bit generous? That would equate to,like 650 torque at crank.... That's diesel territory.

Its a hell of a lot of torque. All 3 runs were within a few ft-lbs of each other. I had also dynoed the truck at the same spot previously on another tuners 87 performance tune and a CAI only. It laid down 299whp and 360ish torque with mid 80's temps. I reached out to the shop today to send me the info from the original pulls to overlay the 2 so that we could see actual gains and where on the powerband. To me, peak numbers don't say jack...its the shape of the curve and where the power is made that matters to me.

Lastly, assuming the 87 tune and CAI added "only" 20 whp:

385 crank * 78% = 300.3whp or roughly 22% driveline loss which i don't think is unreasonable for an automatic, 4x4, 157" wheelbase truck.

Using the same percentages 382whp / 78% = 490 crank hp?
Dare i say 550wtq / 78% = 705 crank ft-lbs?

550+ is very impressive for sure. Full race hit 520 with CAC, DP, Exhaust, and tune. So his numbers are not far fetched.

550 torque at the wheels is very doable. I've laid down that much on my 12 EB with similar mods.
