SlowGray's "old" dyno sheet on 15psi & Amoco 93-octane...

I was going through some old files here on the computer at work and came across this.

Fairly flat A/F ratio scope considering the lack of tuning on the car. Not bad for a stock ecm, MAF sensor car.

what's with the drop in the horsepower curve?

Right there at approx. 4900rpm is what you're talking about correct? This was a third gear pull and that is when the chip commanded the tcc solenoid to lock-up, and at the same time pull the timing back another 2*. FWIW, I already had the converter locked via a manual switch for the pull.

I also wasn't very happy with the guy running the dyno, even though I was doing the "driving". So this was the one and only pull.
