I use a land n sea dynamite to tune my car on. I have never seen a graph as rough as yours. That spike isn't true peak. When a graph is wavy like that the numbers are skewed. I'd say you are 370-380. Any spark knock? That's what it looks like.

Also that graph is observed power. Have him open the file and change it to std or sae. It will probably drop.

I'll tell you that Dynomite dyno is pretty accurate maybe a little conservative. With a CAI inc intake, custom catback mine dynod at 325 SAE corrected. After tuning it pulled 348.2 sae corrected 366 uncorrected. Same exact dyno as the op.

I asked the same question, my tuner didn't hook up his hp tuners to observe the tables. It appears to be knock but I wouldn't know, my tuner only did a wot street tune

I need to get it looked at, but the 397 graph and the 405 are very identical. I'll upload that one later after the gym

I am the Tuner at Unlimited. We use a Dynomite Dyno and were having a Dyno Day this past Sat when the OP had his car dyno'd. Why the graph Spiked like that on his car Im not sure. Could have been knock or lost Communication with the Tach Signal. I'd say smoothed out the Car would make around 380 Which is still very impressive for a L99 Car. If the OP would like I will put the car back on the Dyno and monitor the Knock Sensors as well as check the plugs wires for the Tach Signal to see if we cant get a better looking graph/Pull. Let me know sir.

Typically on our dyno a L99 Stock puts down between 320-335. Manual LS3 Cars around 350-360. Usually we use SAE numbers but for the Dyno Day some people requested Observed numbers and some SAE.

What did it trap in the 1/4 and what was the DA at the track? That will tell you the true power.
