i would think that 190 hp would be possible with increased boost with reasonable reliability, but i wouldnt want to tow trailer with it, (sustiained load). you would need possibly an intercooler and at high limits perhaps water injection or such.

personally mine are all old and i am just tickled pink if they do the stock hp.
