I had the truck dynoed before they started installing the goodies and it only made 295. This seemed pretty low but wasn't sure what they dyno stock. Mine is a 2wd with around 800 miles on it. The shop uses a dynojet. I'll haved modded numbers friday.

What was your IAT temp during the pull? Those #'s seem low for a 2WD, but there are a lot of variables.

I was happy with the tune results of 315.7 HP and 320.8 TQ in our hot Dry AZ weather. A cool, for here, 95 Degrees 1135' elevation at the time of the tune. This is said to be normal tune results for here.

Having the fan kick in sooner by AC pressure makes a big difference in AC performance. If you can stand the fan running a lot...

New paper air filter and 275/45ZR20 Goodyear F1's are the only diffrence from stock.

Why did you stop the graph at ~6100? The engine is worth 6500 RPM and only drops to a little over 297 HP 240 TQ up there.

these numbers are lower then what i thought the LS2 would put down.

my stock LS1 put down 300/312, did chevy de-tune the TBSS like they did with fbodies so they wouldn't be as fast as the vette?

its disappointing to see the 6.0 putting down numbers the 5.7 makes...what's the deal?

There is more drivetrain loss in the TBSS platform than most LS1 setups due to heavier 20 wheels, etc.

We're talkin' apples to oranges guys.... Different Dyno's give different numbers on different days, with different DA / conditions, at different A/F ratios, and even on different dyno runs (one after another)....

If you start hand picking (lucky or singular dyno runs), against other (unlucky or bad dyno runs), you get into these debates....

My Dyno numbers came back ok... but right before me a more heavily modified TBSS failed to even achieve my Dyno results, so "state of tune" or lack there of, has alot to do with it.... :o

very true, but it just seems with fbodies there wasn't so much fluctuation.

i just expected the TB to average 340ish.

340 for a stocker???? (unless it's a crate engine) No way...

RWD 395 X 80% = 316 Theoretical (Most are around 300)

AWD 395 X 78% = 308 (Most are around 293)

Most tunes add some HP (20-25), but loads of Torque.... Like 35 to 40 RWD / AWD...

I Just Dynoed mine today, with 172 miles on the Odometer...
Dynomite Dyno

327 RWHP @ 313 TQ The torque looks weird because I had problems with the Stablitrack staying off.

I will post the sheet tomorrow.

BTW it was 76 degrees inside the shop and the Humidity was down to 3.5% only.
