Update: A small update, but a good one! Today, the ZL1 went to the Dyno for the 2nd time. It was there yesterday for a brief moment. But, they had issues reading my AFR sensor in HP Tuners. But, today was the DAY! They said everything went great, they had the car on the Dyno for around 4 hours, probably some heat soak settled in etc. But, all went great !

They said it was really strong, and it gripped great on the Dyno rollers with the MT ET Street R's! The first numbers with hardly any adjustments was 986 rwhp and 827.7 rwtq (so new base line I guess). I didn't get the boot number. They continued tuning, but decided to call it and they are ordering a new pulley and going to do another dyno day. So, the next Dyno day and probably the final one before I pick up the car will get videoed and I will share that and the Dyno graph afterwards! I'm getting the feeling that another 1000+ ZL1 is in the near future !
