Swapping a stock tbi l19 in my 92 half ton 2wd with nv4500 and 3.42 gears. Currently have a 299 ecm but am gonna replace it with a 1227747 ecm i have here on the bench. I know ill need an ESC modual for a 7.4 and a memcal for the 7747 to work with the big block. I see bins here and cant justifying purchasing a willem or other device to burn a stock chip. Was wondering in anyone would have a stock chip or would be willing to burn a stock chip and ill gladly purchase it from them. Im quite capable of doing the swap as i did the swap on his 1995 yukon to a tbi 454/t350 but required custom programing from tbichips.com. This one should be a basic swap.
