C1500 on 2025 CHEVROLET Suburban

“Welcome! 96-97 have one PCM and 98 and up GMT400's have a different PCM. As far as swapping them over I think you could but since one is a suburban and one is a c1500 it might make things interesting.”

“As far as swapping them over I think you could but since one is a suburban and one is a c1500 it might make things interesting. Someone else will have to answer for sure since I don't 100% know.”

“New fuel system including fuel lines fuel filter fuel pump ..everything literally everything. I can't for the life of me figure out why it randomly stalls I've recently discovered that the ground wires are a little bit rotted so I'm going to go ahead and change those and hope for the best.”

“I've checked everywhere that I could possibly check for any type of air leaks fuel leaks etc. any type of advice would be absolutely wonderful. I'm literally running out of things to change.”

“The trucks in your example would probably deliver similar results. For the Suburban to have the 7.4 it'll be a 2500 so will probably also have 4.10's like your truck.”

“The Suburban is heavier.. by a good amount. Probably the only truck that comes close to Suburban weight would be a crew cab 2500 or 3500 SRW, or an extended cab dually.”
