I HAVE A 2001 GRANDPRIX GT AND WAS WANTING TO GET BETTER PERFORMANCE, BUT CANT FIND ANYTHING WORTH TRYING WITHOUT PAYING AN ARM AND A LEG.
ALL I WANT IS TO INCREASE HP, ELIMINATE SPEED LIMIT, AND TIGHTEN THE SHIFTING. PREFERABLY WITHOUT HAVING TO RUN 93 OCTANE ALL OF THE TIME, OR TO HAVE IT SETTUP WHERE I CAN SWITCH FROM ONE SETTING TO ANOTHER.
