I just obtained a Diablo Sport Predator for my 2001 Z28 auto. For those of you who have one and have been using it for awhile, I have a few questions regarding settings. 1) What temp should I set the fans to come on at if I have a 160 degree thermostat currently installed? 2) Regarding shift firmness, is there any risk of damaging the transmission from setting the firmness too high? 3) Any recomendations for adjusting timing or any of the other fuel related settings? Is it safe to play around with these settings? 4) Regarding shift points, does anyone have any suggestions to improve performance by changing this parameter? If so what is the ideal mph or rpm for the transmission to shift at? Thanks in advance to anyone who read or replied to my long post
