I would say no.

Cobb Stage1 increases the boost level over stock and is meant to be used on a totally stock vehicle. There is every reason to believe that EGTs in a totally stock exhaust setup are very high (not to mention unevenly hot on the 2/4 bank). To increase boost pressures from stock level is to increase the EGTs even more.

I am not saying Cobb Stage1 cars are failure-prone (they certainly aren't) but you are definitely pushing closer to the limits.
