yeah, I'd be replacing them now, probly getting to the limit, but really you can have a low power output and a really bad tune and end up burning a hole in the pistons IMO

I know of a tune shop getting stock internal engines producing 370 plus rwkw. And the customers are using these cars as daily drivers and they are holding together very well.

At the end of the day it all comes down to tuning.

I wouldnt put too much concern on the power figure the dyno reads out at max rpm.

More important is the tune, how the torque is produced in the midrange. The large build up of torque in the midrange is the biggest load under boost on the motor and that can bend rods.

There's cars running in the 400s on stock internals and all is fine, then there are cars that have spat rods with under 300.
