When my '90 SPG was on the dyno a couple years ago, we hooked it up a Motec A:F ratio and someone's injector duty cycle meter (professional gear... the guy's a Porsche/BMW tuner. By 5000rpm the nearly stock SPG was at 100% duty. That car was very close to stock - only upgrades were a red apc tweak (14psi), Magnecor wires, and an HKS bypass valve. Everything else as it comes from the factory, car had (has) 54k on it. In that configuration, hp peaked at like 3500rpm (!) and didn't climb - there was a sharp drop-off at 5300rpm. Torque peaked at 3400rpm (I think) in the 240-250lb ft range and was stable until about 5000rpm. I have the chart someone... I'll try and scan it and post it on my website soon.
