I'm getting a cts2 or 3 here soon, trying to figure out what is the best setup for the EAS. Truck has a FASS 165, 15% injectors, stage 1 64mm turbo, turbo horn, S&B intake, 3" downpipe into 4" exhaust. Has a D5SP switch, BD Tapshifter and a goerend deep trans pan. Just looking to get some good data flow going. It already has a EGT gauge, but having a second one won't bother me. My first thought is fuel flow, air temp, trans temp, coolant temp. Also plan on doing the backup camera for it as well.
