Default Bought a T/A, Came With Dyno Sheets

I can't really make sense of some of the other ones that say mph, or why there is even more than one. The sheets are in the attachments.

On one the hp is a little lower, but the torque is 400! Why is that? I'm assuming the final numbers are 320/344. Car has a lid, unknown catback, and dyno tune. It looks like from the records I got that he also had a dibalosport tuner no. U7198, if it makes any difference. I would rather have 314/409 as the final numbers.

It is a spike. Ignore it.

Yep, ignore the spike. Another I notice is that the numbers are STD. Most people when comparing dyno numbers convert them to SAE. The SAE numbers will read a little lower.

hmmm, so my numbers may actually be lower? Also on the second sheet, I see 266 and 253 at 4100 rpm. Is that the baseline? That seems abnormally low, even for an automatic. I didn't even notice that until I got home, to be honest. What do you think of these numbers? I think it's pretty good, if actual, but I'm new the the LS world.

Looks spot on for a stockish trans-am. Baseline refers to max hp/tq on a stock dyno, not the numbers at the bottom of the rpm range.

As stated before the TQ spike is just a converter flash. Ignore it. That's dyno operator error for recording the run at that point

What I meant was were those lower numbers in the 260 range before the dyno tune? Sounds low. Maybe I was expecting too much after wanting and looking for a an LS WS6 so long, but I thought it would feel a little bit faster. I just got it and already it doesn't feel fast. Maybe I need gears.

You need a stall, my friend. That will wake that pretty much stock A4 up some.

Thanks, I'll look into that. Sometimes I feel like it's not fantastic off the line, but from a roll it's pretty good. There's no TCS button to turn off, so that's out.

Numbers sound about right. After a 3500 stall and 4.10 gears my original bone stock LS1 dyno'd 298 rwhp / 348 rwtq.
