  1. Not sure if it was reflashed when the put the new block in....we did do a new turbo and injectors to get the warranty. Thank you for the reply.....going on vacation next week so its going in for a service...will have to have them check for pressure leaks and check valves.
  2. Hey guys.... I have a 07 ch with e7 460..has 150000 left on warranty. It had 460xt program before we had to drop new motor. Just curious what we could do to get it back to where it was. We cant get mack to install the 460xt program. Anyone else have this motor? Just curious if you had any ecm upgrades or installed any aftermarket turners to get it up to 480-500? Has 18spd 2050 clutch and 3.90 rears. Would a swap of rear ends maybe help?
