I was considering a performance ECU, like the PES Tuning ECU. My car is a '95 850 turbo with up to date maintenance and it's in good shape. 110k on the clock and (most) everything is good on the car. My concern was that I might risk stressing the transmission and the turbo unit with this upgrade. I don't want to shorten the lives of those systems with this upgrade. I'd appreciate any opinions to that extent. Thanks, Steve
