Up for sale is a Haltech Elite 2500T, T is for traction control. Used this ECU with stock coils and also the upgrade Smart coils. For the drag racers the T box is a must! I have been 1.05 with this unit. Nothing wrong with it just upgrading things. Comes with a dual Wideband box, fuse box, and associated wiring. Will require you to wire into car or if by a miracle you can get the PNP harness, yes Haltech has a Plug and Play harness that I used initially, just hard to get. A steal at $2250 shipped
