    LB7 or LLY

    I'd say either would be fine but my vote goes to the LLY. To get past 500hp your going to be looking at a turbo change so we can rule out the difference in turbo's between the two motors. I prefer the injectors on the LLY because they dont have issues like the LB7's are known for. The rest of...

    LBZ: fuel return line

    Well PPE does sell the "race valve" which is essentially just a block off for the FPRV to prevent any sort of fuel pressure relief at all. I shimmed mine up so hard that it wasnt capable of lifting anymore and I never had any problems. not saying its the right way, but it worked just fine with...

    Allison 5sp: Converter locking too hard

    This is a stupid comment... but what about your u-joints? Sometimes its tough to know when they are starting to go bad. But the truck will feel like it shifts terribly, converter lock up feels rough and going from R-D or in and out of park always clunks. You'll know pretty quickly if you keep...

    Cleaning heads

    Use a toothbrush. I used a few and they worked fine for the exact same stuff - intake runners etc. I recall using brake cleaner on the intake stuff. My heads were cleaned at the machine shop. I would ask the shop you take them to what they do for aluminum heads just to make sure they dont hot...

    How about an $800 Hydra-boost hose......

    Edson!!!! That sucks man. I could think of about 300 towns I'd rather get stranded in than Edson. Lets start with high prairie... grand cache maybe... balzac? La Loche saskatchewan... Haha, maybe not. Me and Edson don't have a good history.

    Turbo change on LMM

    Already sent a PM or email or something like that. I'll give him atleast 2 days to get back haha. I noticed that not many vendors are quoting anything for "LMM turbo kits". Like I had asked initially, is there something different about changing the turbo on the LMM's than the other models? I...

    Turbo change on LMM

    Is anyone making a twin kit for the LMM other than MPI? Their product seems to have positive feedback, but do I have any other options? The HTT was a good turbo, I guess there is no reason why I wouldnt put another one on.

    Turbo change on LMM

    Ya. The obvious choice is the twins. I'm just cheap and looking to see if I can get something in between. To be honest I'm considering buying a 2008 Z06 vette instead of spending money on the truck. I'm just trying to get it all figured out and compare the cost-to-usefulness/enjoyment ratio's.

    Turbo change on LMM

    Is there anything tricky about changing the turbo on an LMM? I switched to an HTT 66 on my LLY and was really happy with it. I'm thinking about doing the same on my LMM but to be honest I havent even looked under the hood of it to see what is different. Any experienced opinions on a larger...

    fueling problem-60%,dual CP3

    Sounds like its in limp mode for fuel related issues. Are the limp mode tables altered from stock? Do you have the limp modes disabled by other means? If you dont, are the codes set to not report and thats why nothing comes up?

    Engine Power is Reduced

    Mines does this too. First time happened when I was unloading my sled off the deck... it was frozen to the deck and the truck was moving back and forth quite a bit as I was trying to get it off. I heard it beeping and I got in the cab and saw the message. Next few times were just driving around...

    Just bought 05 cc duramax, low coolant!!!

    If you do it yourself it can be done fairly cheaply in about 20 hours... For me gaskets were about 150-200 a piece and the head studs were 600. Copper washers and O-rings for the injectors totaled about 100 bucks. Head alignment dowels were like 5 dollars. I took the heads to get checked/milled...

    New BMF Novakanes

    That looks good. I like the BMF wheels. Has anyone seen the "rehab" model? I got a set on order. The new satin finish "stealth" models of thier wheels look good too. I debated a set of the stealth novakanes for my 08. The truck is black so I'm going for the blacked out look.

    NBS gauge mount options?

    Hmm. Guess I'll have to resort to a pillar pod. I just hate when the gauges are blasting you in the face. Especially at night. I'll have to put the lights on a switch

    NBS gauge mount options?

    Recently picked up a 2008 GMC Sierra SLT and I would like to put some gauges in but I'm not a fan of the pillar pods. Is there any other options available? I've been looking but couldn't find much of anything

    There is an electronic selector for P,N,D... I can't think of what it is called off the top of my head. Someone here should know. I'm pretty sure its on the transmission... I'll bet thats the problem though. Shouldn't be too expensive of a fix. And if I recall right anybody with a couple basic...

    FrAme mounted fuel filter and pump?

    Ya, I got my parts guy looking into some prices for me right now on a FASS setup. We'll see what it is. Ordering off the net seems cheaper but its really not once I get it shipped across the border and up north. As for bypassing the stock filter housing... I was just going to unbolt it and take...
