The car was back in the shop to eliminate lingering bogus codes from the de-wire and to get the dyno tune. The dyno tune found 20 more hp from the off-the-shelf performance tune. There is an odd dip in hp at 7,200 rpm. Tuner thinks this could be some kind of harmonics with the exhaust as he wasn’t able to get rid of this. It’s not noticeable when driving the car. I do like the flat torque curve. I assume this is due to the stepped header design. Absolute values aren’t entirely relevant since different dynos and different days will produce different results. Motor is stock, with Supersprint stepped headers and catless exhaust and underdrive pulleys.
