Thanks for posting the graph. The torque gains at the bottom end are impressive. I have a few questions, if you know the answers. Did you have a tune before the manifolds? It looks like a 3rd gear pull that was ended real early because the torque line never crosses the hp line. Also my car shifts into 4th. around 105 so it looks like you were shutting it down real early. If that's the case you have another 20 hp on top thats not being shown. I need to find my old dyno that was done in MPH to be positive. So you don't feel weak with the high numbers posted by others, my car was around 260 hp stock on a Mustang dyno. Any idea what the AFR's were?
