[QUOTE="guevoncito, post: 16994645, member: 204128"] Hi Everyone, Update. The light still stays on all the time now. Car was on the dyno yesterday with datalogging. Tuner is happy, car is healthy. Still no real answers for the 6250 to 7000 light. No codes or CEL. Here is an interesting side note related to the blower rebuild. The blower rebuild seems to have improved the blower's efficiency. On the 2.875 pulley and 24-25# of boost, it previously made around 975 HP and 915 Torque. On the 3.75 pulley and 17-18# of boost, it previously made around 830 HP and 760 Torque. With the blower rebuild, the 2.875 pulley made just over 1200 HP and 1000 Torque. With the 3.75 pulley, it made just over 900 HP and just under 800 Torque. The 2.875 setup was way too spicy for my taste, so I opted to stay with the larger pulley. Also worried about the transmission lifespan at the 1200 HP range. Plus the traction challenges. Just not fun to drive. We're still tracking down the issue with the RPM light. The tuner couldn't find anything or force it to behave. Current suspicion is the oil temp sensor. Main concern has been mitigated about the car's health after the blower rebuild and reinstall. If we ever figure out the RPM indicator issue, I'll post back. Thanks everyone for the inputs and guidance! [/QUOTE]
