Since I don’t know much about tuning all I can say is the LQ9 is supposed to run 91-93 in stock form, and your tune is for an LQ4 on 87-89 which seems to me could very well be at least a part of your problem like everyone is saying. I agree you should at least run Premium in the highest octane you find locally and you need to get it re-tuned.

I def will.

Reading this again I see what BTR was saying. You won’t benefit from higher octane if you don’t have the high octane table set up in the program. This is true. BUT, it will keep it from pulling timing due to running low octane and sensing knocks. So theoretically, you will never get optimized timing without setting up your tune but you will run better and at least keep the knocks down.

Exactly

Something with the tune you think? Gonna try to get another belt tomorrow. I googled for an 05 Silverado HD 2500 with 6.0 and 160 amp alt. Came up with this acdelco 6k930.

When you get your belt, get a can of brake cleaner and a brush, and clean those pulleys.

I was just looking at an LQ4 table Monday and I remember it being very very conservative but it was in a 2006 2500 which I think they may have detuned the timing table even more for towing long grades. Anyway I can't imagine the lq4 low octane table in a suv being very aggressive but I guess any knock will start to pull timing.

Changed the belt. Went down 1 size, seems ok. Now the starter went--I'M STUCK!

How’s the alignment between alternator and power steering pump look?
