I went out to the Utah Diesel Nationals this last weekend. My truck has never been on a dyno before and as my buddy and I were watching a few of the trucks I knew I had to do it.
I am waiting in line and two guys about my age, 23, are right next to me in a LB7 duramax. We start BS'n and talking about our trucks. He has never been on a dyno either so we are making some guess, he has a "6" stage edge juice, exhaust and intake. He is hoping 500 HP, but to be realistic he says 450 HP. He sees my stack and asks what I've got, tell him "just an SCT nothing special".
He went right in front of me and...
first pull stock - 262 HP
second pull edge "5" - 321 HP
third pull edge "6" - 323 HP
The guy with the dyno drives a twin turbo 6.0L so he was pretty interested in my truck
First two pulls I got on it to much and down shifted, but made 350 HP before each shift.
third pull - 387 HP
fourth pull - 379 HP
The dyno guys where very impressed, printed my sheet and gave me a card for his shop. Said that truck is 400 HP at sea level.
Thank you Eric, Innovative diesel for the awesome tune (Extreme Street). The dyno chart is amazing, it shoots up past 350 in a hurry and stays over 375 from 2300 to 4000. Its a super broad power band!!!
Duramax guy didnt say much to us after the Dyno
On side note I got a ride in a duramax with MPI twins... WOW
just a little faster than the stroker...
