I'm looking into tuning solutions for my turbo'd '90 GT. I am curious if there is anyone using a quarterhorse and doing their tuning with TunerPro RT, or if it would be worth forking out the cash for Binary Editor. I'm leaning toward the quarterhorse because of its emulation capabilities, the ability to retune without removing a chip, reburning and reinstalling the chip, as well as its cost effectiveness. I am open to other suggestions and would like to hear about what others are using and their thoughts about their setups.
