425 whp was the number in this video, its definitely making more. Tune is safe now, so at dyno day we will run it again. If my memory serves me right, at the first dyno day there was a red drag camaro with a 383/stall/p600b and he did a pull similar to this, and it put down about the same. Its the way the converter loaded. Car is definitely around 525, now just to prove it. Converter was definitely unlocked.

Time for a vanity plate that says "425RWHP" and fill up that bank account at the grudge races.
Osie said he's gonna go to island and show people the 425 whp dyno sheet lolQuote:

I would have done locked runs and "stalled or flashed" runs. I don't know why they wouldn't lock it.
Before I jump to conclusions on what's going on I would need to see a dyno graph.
But...
It's a 3200 9 inch converter its not robbing all that power.
With that said dynos don't mean squat they are for rough tunes before hitting the track or street for final tweaks.
I would ditto the idea of seeing cars pickup 100 horse by locking up. Unless that converter is complete crap I don't see it happening though.
One. It should've been locked. Two. He didn't lock the car in third gear either. 3 the data log should've showed if it was down on power. Motor alone made 490/490 na on an engine dyno. So 425whp for an auto with no boost should be correct. But this had 8psi on top of it, idn why the hell its not showing what it should.Quote:

I'd find a different dyno quick and just toss it on the rollers. From everything I've ever seen, that dyno spun up so fast that you can simply hear it's making WAY over 425 RWHP.
I found a video of a dyno run I did when I was still running gas. I believe this was the run that it made 593 on. Converter locked. This was after the 2013 shootout and it had ran a best time of 10.39@131 @3750#. The Wallace racing HP calculator estimates it at 595-615 RWHP.
Locking the converter should help make the numbers look better, but the important thing is that the afr and timing are dead on. The proof is in the et/mph, not so much the dyno number

What afr reading is it seeing and total timing?
Id agree with fastbird and gm powered about the trans converter. Yes its an auto, but it that 9" core.should be good assuming it was spec'd for the combo, but I'd say it should make 500 plus. If it drives good, sounds healthy, and seat of the pants feels good id take it to the track. Id like to see 125 mph traps on 3500 lb f body with your set up.
Well it sounded pretty healthy in the video. As mentioned, if the tune is good then just see how she does at the track or the LTxTech dyno day. It would be interesting to see a graph.
Still waiting on the rest of the info, that was all we received today. He said the tune was spot on, second pump now works correctly
