Hello GM fam, I need a little assistance. I have a 91 v2500 suburban with a 350 motor and a 400 trans everything is stocked. I want to add some more horsepower without spending a lot….I want to change my intake and my tbi just need a little advice on a good combination to use as far as what...
I’ve been having a hard time trying to record the sound but I did the best I could, but I’m trying to figure out how to upload it it’s only going to my photos and videos
I have an obd 1 not a Bluetooth but there’s no codes. I read that some times if they are bad it would give a rattling sound during acceleration. I used to use premium gas but I switched back to regular when my truck was running rough, but I always use fuel treatment in my truck also.
