Coolant is bled, base ignition timing is set to 11 degrees BTDC (I know stock is 10). Drove it for about 20 minutes straight, hit full boost twice, and the temp stayed right on the 7th mark on the stock gauge and my aftermarket gauge stayed inbetween 195-205F. TSRM says that full thermostat lift is at 212F and I didn't even come close to that so I think its ok. Only time will tell...........
