    FPR performance code

    I've read other posts, and can't find anything that helps. I only get this code when it's cold out, like under 70. I thought it would've been gone with efi live, but it's not. LP runs at 11psi at idle and truck runs normal. I'm at a loss.

    New lights

    So I bought all new lights. Everything is led minus the low/ high beam. Those are the zxe bulbs. I'd like to do the front fogs, but not willing to spend the money for them to be factory. Sent from my Moto Z (2) using Tapatalk

    Blower motor doesn't work on spd 5

    Ok I've done research and can't find anything. I've changed the resistor/ relay. Tried a new blower switch and still nothing. It work on all but 5, relay clicks when going to 5 and I've checked all fuses. My truck doesn't have a 40a fuse under the hood for the blower. But I've checked all fuses...

    Airdog 165 pressure

    Ok installed it when I did my injectors about a month ago. First primed start up I had 12.5psi got the p0089 code. Erased it and lasted bout a week before it came on. Now my pressure has raised to 15psi and I get the code every could of days. Is it normal for the pressure to raise by itself? And...

    New shoes

    So went to discount and they wouldn't put 285's on the stock wheels, so with my hookups I just went ahead and bought all new. Not a bad looking wheel for the price. Sent from my Moto Z (2) using Tapatalk

    Installing gauges on lb7

    Ok I've bought a 3 pack gauge setup. Boost egt and 30psi fuel gauge. After some research I know to put the egt probe on right side manifold. Now I've heard of several places to put the boost gauge, but I'm not sure where the best place will be. Also where's the best place to put the fuel gauge...

    Finally I can do injectors

    So I've been beating this to death, stock remans or sac's. I know sac's run better and a better design, but if a stock internal lb7 can only hold roughly 5-550hp, and you can tune stocks to accommodate that, then what's the big pro of buying sac's? Plus I just found out I'll have to have a tune...

    Lb7 build

    Hey guys, I'm leaving on Saturday for the oil fields. So here in a few months I want to start building my truck. I've watched a lot of videos and read a lot about the problems with lb7's. My goal is 800-1000 if possible with a single turbo setup. What I'm wondering is what would be the best...

    Loping idle

    So I've been doing a lot of research and I'm still not certain on what's causing my issues. Some say I need injectors, but then someone else has roughly the same problem as me and it's the fpr. I tried to upload 2 videos, but it says files are too big. Could someone pm me their number or email...

    Think my TC is bout done

    Every morning when I leave for work, I get on the highway and it takes about 5-8 miles before my trans goes into OD. I've noticed once it warms up some it works better, but I think it's just tired. How hard is it to rebuild these transmissions? I am an ase master diesel tech, but I'm not...

    Performance mods to hp gains

    Ok, correct me if this is unrealistic. I'm shooting for the 700-900hp range. 60 over SAC injectors, Duramax tuner 68mm turbo, dual fuelers, 5" exhaust with true 3" down pipe, true 3" hot and cold pipes, bigger CAC, and efi live. Am I even in the ballpark for the power I want? Any ideas...

    Blower motor speed

    So my blower motor hasn't been as fast as I think it should be, so bought a new motor, installed it and same thing. My brother has a lbz and on high it'll move your hair and cool down his CC fast. All speeds work on mine, I'm just not sure if there's supposed to be that big of a speed difference...

    2012 Yukon helper bags

    Hey guys, my buddy has a Yukon Denali with rear air ride. When he pulls his toy hauler, it's a bit much for the factory air ride. Every kit I've looked for says without factory leveling system. Anyone know of a air bag helper spring kit that can be installed? Or do I need to remove the leveling...
