So who's got a decent aftermarket reprogram of the ECU for the 2.0 turbo in the Optima these days? I've got a long history of modding 1.8T/2.0T/2.7T Audi and VW engines. We're often able to get 40-60hp with NO change other than changing the fuel maps to take advantage of 91/93 octane gas and upping the boost to about 1.2bar. Anyone doing that for the Kia engine yet? If so, how's the reliability?
