    Need help with swapped 02 silverado

    So I have a 2002 Chevy Silverado 2500HD. The truck came with the 6.0 gas motor which cracked a conecting rod and through it through the side of the block when I hydrolocked it :/...So I bought an all aluminum LS1 out of a 2002 ss camaro (5.7 350) and just swapped them out using the stock truck computer. It runs ok but seems to idle funny, shifts at strange times, and occasionally misses. I'm wondering if tuning would fix this or if I have to get the camaro computer.

    I'm thinking both may be in order, I would see if you can get in touch with Steve from Tuned by Frost he is very busy but sometimes he will answer emails. Also maybe repost this question in the computer section he checks in to there from time to time

    Tuning by Frost will fix this. It's not necessary the ecm.

    Welcome to the site! Even though you swapped all your truck stuff over to the 5.7, it differs in a number of areas which have to be accounted for by adjusting the tune. As you are experiencing it is close enough to run... just not very well.
