I found a deal on a used (incomplete) Accel setup that is basically just TB, manifold, rails & injectors. However, it's a 1000cfm TB and a nice manifold, so I'd like to install it on the Camaro. The Accel wiring harness and ECM is $1700! So I'd like to run it $OD with a 7427 since I'm already familiar with it in my truck.

Now, what would be the best way to get a baseline tune on a truck ECM with a fairly healthy engine? Wiring it up doesn't seem like it would be too bad, but starting from scratch on a tune with a healthy camshaft sounds daunting...
