Local shop owner and good friend held a dyno night for diesel trucks about a week ago. Truck put down 556.7 hp and 1055.8 ft-lbs tq. It has had this tune in it for the last 3 and a half years and hasn't skipped a beat! Very happy with the numbers but have a few more up grades in mind to get a little closer to 600.

 

Welcome? Lol.... Dyno sheet? Pics of the trucks? Vids of the pull?

 

In for info, what mods?

 

THem Duramax's will put down some power,Buddy of mine has an 06 and Black Bear did like 4 tunes for him..He can switch them with a switch, one night he showed me what the big tune could do..Dropped it in 4high and spun all 4-tires for a second or 2 and when it cought..WOW..

 

Specs on the engine and the rest of the drive train?

Are you running a stock transmission? Kind of getting up there on the top end of what it can handle.

 

Truck has the following: Suncoast stage IV trans and 1056 converter, Fass lift pump, Banks CAI and hot side boost tube, dual 4'' exhaust, MBRP downpipe, egr blocked, fprv shimmed, EFI live and some suspension parts to keep the tires pointed straight during 4x4 launches. Have a few parts to install yet( High flow Y bridge and cold side boost tube) and i would like to get a set of up pipes and manifolds. Hopping for around 600+ hp but would like to keep the tq where it is or lower. Don't want to bend my rods so gotta keep the tq down!

 

I'll get the dyno sheet and pics of the truck when i get it back from the shop. Had a dent in the rear door passenger side that is getting fixed. The bottom of the truck from the body line down is also getting painted. Truck looked kinda funny strapped to the dyno with the front bumper and grill missing.
