Just put a Racepak Sportsman in the car this winter.... I've got ALOT to learn! Cool seeing how high the converter flashes after tbrake release. Seeing actual shift rpm in relation to your shift light..... and noting how long my 1-2 shift was takng in relation to my 2-3..... Self inflicted hydraulic leak was slipping the band. Eventually I want to add oil psi, coolant temp, and one O2 sensor at least. I bought mine used at a lil savings...
