what do you guys think. stock

 

oopppsss

 

The downhill decent...looks stock.

Go aftermarket and fix that boost taper (reason for downhill power) for more power!

What was different about that middle run? The first run, and last run are a lot lower than that middle run. Makes me edgy to see dyno charts all over the place like that with no tuning added into the mix.

The car is warm and ready. It was a bit cold and it was setting for hr before the run.

 

adjust the A/f too, you are going off the chart rich, that surely will pick you up some ponies.

 

What's with the dip between 5000 and 6000 RPM? Is the AFR or combination of boost taper causing that?

 

Thats the classic "bone stock" chart.. He's right, the different numbers are because the car wasn't "Up to temp" usually can take 2 or so runs to get the car warm and consistently in closed loop.. the dip is when the boost control solenoid is about when it kicks in and tapers off.. over 6000 is where it gets monster rich (same as my car) both contribute to a stinky off the scale rich condition. (if you haven't already noticed, the car seems to have originally been designed NOT to taper boost, but was likely done as a safety device later in its development)
