Looks like maybe if not for the dip it would have made more?

Dip looks like something is wrong. Did the belt slip or something?

^ Agreed, looks like its choking up top, takes a dive early. How is the fuel delivery looking? Is it flooding meth up top? Might be a bit rich at the tippy top?

Car is tuned great but I honesty think the dyno situation was not breathing, clearing the exhaust fumes out good enough. The car was already tuned very close I mainly just wanted to see what it does and maybe try some timing changes to see if more power was on the table. I kept having to lean it down and on the last pull car went to 9.5 to 8.9 from 5000 to about 6000 and broke up and back fired so I let out. Had done maybe 6 pulls and that was the last one we did so I dont know. When I left and got on the street I had to richen up.
Also maf reading was low but strangely the ms injector went to 7.5 and high pressure pump went from about 2300 psi down to 1400 it has a stock fuel system. Seems kina backwards. |

I guessing that dip is not normal? I dont notice it on other graphs posted here, I dont know first time I was ever on a dyno.

Sounds like your fuel system is not keeping up. If I remember correctly your ms on the injectors is supposed to be 6.0 or below. This looks like a ticking time bomb especially if that meth stops working.

Look at your logs. The timing curve should be pretty flat at WOT. I have a hunch that you will see a big dip in the timing at 6,000 RPM. Your tuner can correct that.

Here is an N/A Camaro log with a red box around the timing graph. The white line is the timing. Notice that there are no spikes or dips.

timing looks great less than a 1 through the pull. only thing changed was what i said early. The graph I posted was the pull right before that one.
