The module arrived and was packaged well and in good shape. Not as easily installed as I thought it would be. Sure it is plug and play, but the original wiring harness had a couple of ridges or raised slots that helped in the alignment of the harness into the original ECU. The male side of the module has those ridges, so aligning the module on the original ECU was easy. The femaale side of the module does not have the raised slots, so care must be taken to ensure all is aligned as it should be.

After completing all suggested mods from jet perf. for the stage 2 chip i rove the truck to compare before and after chip. i was pleasently supprised with the extra torque and HP gain. My hole shot didnt really change, but the increased pull threw the mid to top end off each gear was impressive. it felt like a mini supercharger... My 60mph roll and launch was also much better. 60-80 in seconds with half throttle.. (not bad at all for stock block) The MPG didnt change much, maybe 1-2+.. over all a great bang for the buck when you have an externally moded motor.
