hi guys.
i am new to this site, but someone gave me this link and told me that this is the place to probably find some answers to the questions i have about my ls1 swap. i have a 1998 gmc sierra c1500 sl, i just bought a 2000 trans am ram air ls1 and 4l60e to put in it. i have the ecm, wiring harness, throtle control, and radiator and fan. my biggest concerns revolve arround the ecm reprogramming and fuel pressure. would someone care to give an idea as to where to start?
