I think the only way to tell the difference (if any) would be with a dyno run. I don't think that chipping the car has really added much horsepower but it certainly has added to the drivability of the car. I have the throttle response up to "9" now and I can adjust the air flow and most importantly the timing. The torque line is much flatter now. I think you will enjoy it. Please post your impressions after it's done no matter what. I was really tempted to go with GIAC too but in the end the little programming box got me. I think GIAC may be offering that as well. You may want to check into it. Good luck with the reproramming!
