Do people have two plus years of running a Cobb? I just ordered mine. I have some concern regarding the turbo longevity at the increased boost level. The Cobb essentially doubles the psi yet we only net 50 rwhp. That lends me to believe the turbos are out of their efficientcy range. My previous car was a rx7. As a point Of reference, adding 50% more boost, going from the stock 10 psi to 15 psi netted 130 rwhp. Intuitively it seems with the 335 the turbos will be working very hard but producing little. Are people's turbos lasting at these boost levels.
