I got my 4.30's installed today in my 99 auto. I bought a superchips microtuner to calibrate my spedo and change the shift points, etc. I could realy notice a difference whan I changed the shift firmness but I cant tell the difference when I adjusted the shift points. It seems no matter if I adjusted it to max or min or just left it at stock, which is in the middle, my car is still shifting way too soon. When I ease into the gas from a stoplight the cars is in third gear before im even going 20 mph. Anyone have any experience tuning an auto?
Anyone familiar with superchips micrtuner 1725?
