Anyone dynoed a stock 2nd gen?

I have a 2017 NA limited (5.7 FFL). Anyone dyno tested this gen stock? I know its rated 381/401...just wondering how much hp/torque its losing from the drivetrain and restrictive stock exhaust....

 

If you browse thru the stage 1 harrop thread. A few guys posted the before dyno

mine was 287/310. It was a 90degree shop. Houston

most folks are 300/310-ish


I’ll add. I have a trd exhaust. No other mod at time of dyno

 

I highlighted the base run.

the other run is untuned Stage 1 Harrop. 6psi-ish.

this is a '20 - I doubt it differs much from yours.

 

My stock run was similar to @nobodyintexas w/ 297HP/334TQ

Not sure there is much to gain from the exhaust but @dirtydeeds could answer your question.

 

DD exhaust will give 3-10HP and 10-20 torque, depending on rpm in a stock truck.

 

They’re good for 335 Hp to the wheels on a dynojet. Simply fitting off the stock muffler is good for 3-10hp

installing long tube headers with a BAmufflers 3” race exhaust is good for 49hp

 

where in the rpm range is the gain?

I'm guessing up top?

 

That was my misconception also. Until I dynod it. With a properly built system such as the Bamufflers system, ALL of the powerband shifts ‘up’. There’s zero loss anywhere but gain everywhere.

 

Who'd you get to install your SC, or did you DIY? Just outside Houston and looking to get an SC in the next year or two

 

Peitz Performance did mine.

Prospeed is good, too.

D3 performance did my Stage 2 tuning.

 

Awesome, thank you.
