Default SAE or STD? It doesn't say..

I got my car dynoed and the sheet they gave me doesn't say whether these numbers are SAE or STD. Besides asking them is there a way to tell?



By the way, what do you think the numbers should have been after a tune?

Car has Pacesetter LT, ORY, Flowmaster cat back, LS6 IM, stock TB, SLP lid, no free mods.
Car also have LS7 clutch with the heavier LS2 flywheel.

i think your numbers are horrible, corrected or not.....

stock the worst you should be is 280rwhp

the A/F is WAY LEAN and thats where youll get all of your power back.

your car tuned should be putting down at least 320-330

Wow, 16:1 AF at 4000rpms, I guess that's why the pull stopped shortly after a 4200ish rpms. Get it tuned and redyno, like Brandon mentioned in the previous post you should be 320ish rwhp SAE with longtubes and tuned.

You saw he pulled out at 4,000 because it got too lean right?

Yeah and you still made 308rwtq by 4k, torque still didn't peak and hp not even close. Get a good tune, it will make power.

This is what I made, only made 3 pulls total. The first one that I posted. Pulled 305 the second time and this the last.

Putting the cam in this week so no point to keep tuning just getting it driveable.

Yes, I understood that. Thats how they all work, I just didnt know where it originated or when it became popular.

Haha, even with the horrible tune, that ridiculous table of a torque curve should have given it away that this was not an LS1.
